I am facing an issue while trying to request user certificate from a Microsoft CA on IIS7/Windows Server 2008 R2.
For requesting certificate, I am using the CCertRequest submit method.
In my logs, I have the following error :
CCertRequest::Submit: The RPC server is unavailable. 0x800706ba (WIN32: 1722) COMException at CERTCLIENTLib.CCertRequestClass.Submit(Int32 Flags, String strRequest, String strAttributes, String strConfig)
and the associated DCOM error in Event Viewer :
DCOM was unable to communicate with the computer
cert.XXX.com/XXXCA using any of the configured
protocols.
When I ping the CA using CertUtil command tools, the command is successfully :
C:\Windows\system32>certutil -ping -config "cert.XXX.com\XXXCA "
Connecting to cert.XXX.com\XXXCA ... Server "XXXCA"
ICertRequest2 interface is alive
CertUtil: -ping command completed successfully.
Do you have any idea to help me ?
I fixed it!
The valid configuration string for the Certificate Services server is
ComputerName\CAName
and not
ComputerName/CAName

I am using a third party library (MinIo dotnet SDK) in my .NET application. I successfully send the requests on the localhost, but at the time of publish on the IIS server, the requests are met with the following error.
MinIO API responded with message=Connection error:The SSL connection could not be established, see inner exception.. Status code=0, response=The SSL connection could not be established, see inner exception., content=
Same problem here this week.
We had to install the (root) certificate we used for our minio/S3 server on the machine we ran our application on.
If you don't want to use SSL, you have to use MinioClient.WithSsl(false).
i followed all the steps mentioned in the below link
https://learn.microsoft.com/en-us/analysis-services/instances/configure-http-access-to-analysis-services-on-iis-8-0
But when i connect to http://servername/OLAP/msmdpump.dll in my SQL Server Management Studio i get the below error
TITLE: Connect to Server
Cannot connect to http://ServerName/olap/msmdpump.dll.
ADDITIONAL INFORMATION:
The connection either timed out or was lost. (Microsoft.AnalysisServices.AppLocal.AdomdClient)
The remote server returned an error: (405) Method Not Allowed. (System)
I wanted to make a ODBC connection from Windows PC to AS/400 DB2 server and I wrote a VBA program. But I got the following error.
Remote port could not be resolved
Then, I checked the status of server with CWSPING and got the result below:
I - Verifying connection to system 192.168.1.2...
I - Successfully connected to server application: Central Client
I - Successfully connected to server application: Network File
I - Successfully connected to server application: Network Print
I - Successfully connected to server application: Data Access
I - Successfully connected to server application: Data Queues
I - Successfully connected to server application: Remote Command
I - Successfully connected to server application: Security
E - CWBCO1011 - Remote port could not be resolved
E - CWBCO1008 - Unable to connect to server application DDM, returned 8407
I - Successfully connected to server application: Telnet
W - CWBCO1015 - Connection verified to system 192.168.1.2, but there were warnings
This means DDM service is not working on the server. ODBC connection requires DRDA, which runs upon DDM service, so I think running DDM service is the key to make ODBC connection. So I tried STRTCPSVR *DDM command but got the result below
*DDM not valid for parameter SERVER
And also tried CHGDDMTCPA AUTOSTART(*YES) PWDRQD(*YES) command, but got an error and I got stuck.
Command CHGDDMTCPA in library *LIBL not found
Does anyone have an idea of enabling DDM server on AS400?
Server: IBM AS400
OS version: V4R1
Try STRHOSTSVR *DATABASE.
STRHOSTSVR is used to start servers associated with IBM i Access and i Access Client Solutions.
STRTCPSVR is used, in general, to start servers associated with TCP/IP like FTP, Telnet, etc. Except the HTTP Server which is started via the Web Administration site at http://<server>:2001.
Additionally to the answer from #jmarkmurphy:
You can easily check netstat *cnn for open ports.
There is actually a tcpsvr named *ddm but that isn't used with ODBC.
ODBC-Access only needs host server *database. There aren't any further requirements for host servers.
For checking which services are started at tcp startup time, use strfdu, option 5 with the file qusrsys/qatocstart. From there you can easily view and change what should be started and what not.
Finally, I got connected by using JDBC. The summary of what I found is as follows:
ODBC seems using DRDA(port 446) but the server does not have DRDA/DDM service
OLEDB seems connecting Data Access(port 8471) but issued unknown error
JDBC also connection Data Access(port 8471) and it worked!
The first error I encountered when using ODBC is "Remote port could not be resolved". What happened behind this seems as follows:
ODBC asked Server Mapper(port 449) to find DRDA port(it may change on a server)
Server Mapper could not find DRDA port because the server has no DRDA service
ODBC showed "port not resolved" error
Then, I tried OLEDB this time. It checked user/password correctly but issued unknown error. When I put incorrect password, it showed "password is incorrect", which means OLEDB successfully log on to the server but got some error after sign on.
The last, I used JDBC and successfully connected! Generally, the connection url is like "jdbc:as400://" but it showed error. Using trace of JDBC, it seems to have problem on sign on to the server. So I changed the url to "jdbc:as400://:8471", then I finally connected. Looking into trace, it directly access to port 8741 and send user/password and get connected. I don't know the detail, but it worked!
Appreciated for your help!
I got 2 servers with two equal wcf services hosted on them and one client application server. I can connect to endpoints and send a requests to both services using test wcf client app (.NET Web Service Studio) from my local machine successfully. But when I am trying to connect from client application server using the same test wcf client app I successfully connected only to the one wcf service server, but I have got an error when connecting to another one:
System.Net.WebException: There was an error downloading 'https://XXX/XXX?wsdl'. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it XX.XXX.XX.XXX:443
I performed netstat -an | find "443" command in command prompt on the client server and on my local machine to find out the difference and here what I have got:
1. On my local machine:
2. On the client app server:
What I already tried to do on client application server is:
- turned off firewall;
- stopped windows firewall service
- uninstalled mcafee virusscan enterprise application.
(I tried to set "prevent mass mailing worms from send mail" first, but mcafee was in foreign language that I don't understand, so I just uninstalled it)
after running command netstat -aon | findstr "443" on client application server I have got this result:
but I still got an error.
Does anybody know how to solve this issue?
Could be the problem on the wcf service server side?
The solution was predictable simple one - firewall was blocking the port,
but it's important to notice that the issue was caused by firewall on the wcf service server side, but not on client application server, which is making the request to that service.
I asked the technical support of that server, and they made firewall changes.
After that error was disappeared.
I faced the same issue and tried different ways to fix this. Nothing works. Later i found the issue which is, the application i tried to run is https and in my IIS, https binding was not created. I created binding https with the website and it works.
I have got a simple BizTalk Application in which there is only one schema and pipeline. I have simply add XML Validator in validate stage of pipeline.I have deployed this app in BizTalk Server 2010.
Now I have created a receive location which takes a XML file and set its receive pipeline which i have created. I have also marked "Enable routing for failed messaged" in receive port.
I have also created a SMTP send port and and configured it with mail server name and etc.
Receive port is working fine but send port is unable to send emails.
When i check "Track Service Instance" is shows an error "Transport failed to connect to the server".
Update: I am using Gmail SMTP server name in order to send e-mails and I am getting the error "The server rejected the sender address. The server response was: 530 5.7.0 Must issue a STARTTLS command first. ye1sm22267001pab.19 - gsmtp"
Where could be the problem? Any help will be appreciated
With that error in your update the problem is clear.
The Gmail server is expecting a SSL connection.
See SMTP TLS problem
The standard SMTP adapter does not support SSL/TLS connections.
You will need to write a custom adapter or purchase a third party
adapter to support SSL connections

Greg.Forsythe
EDIT: An alternative is to connect to a local SMTP server that doesn't require SSL/TLS and let it route the e-mails.
Are you running 32 bit or 64 bit? Is your tracking host in 32 bit or 64 bit? MIME/SMIME encoder pipeline can't run in 64 bit mode... are you using that?
http://msdn.microsoft.com/en-us/library/gg634591.aspx
"Transport failed to connect to the server"
This error message basically means the BizTalk SMTP adapter is unable to connect to the SMTP server or the server does not allow to send the e-mail.
Try connecting to the SMTP server with the telnet client (you may need to install this as an additional feature) or by configuring the proxy (available on the SMTP adapter and adapter defaults).
It might also be the case that you need to authenticate towards the SMTP server.
Also, some SMTP servers do not allow to send an e-mail from an unknown domain like "someone#notthenameofthecompany.com".
Hope this helps.
