Windows server 2008 & Opendns - networking

I have a problem, my network have a domain controller, File server, DHCP & DNS server configured on one machine, i would like to filter the internet content using opendns.
but there is some computer on the network should be excluded from this filltring.
Keys:
1. Computers get IP configuration by DHCP.
2. Computers DNS & Alternat is the local server (Could not be changed).
3. Client Computers are mixed (Windows XP SP3 & Windows 7).
4. Server OS windows server 2008 R2 64 bit.
Any ideas please?

Simply put the OpenDNS servers in the DNS Forwarders tab and configure your DHCP to deliver your Domain Controller IP addres as a DNS Server for your clients.

Public HTTP Port Forwarding Fails on Windows 8.1 Update IIS 8.5

I have three Windows hosts on the same private LAN, each hosting an IIS default website. One host is running Windows 7 Pro, while the other two are running Windows 8.1 Update Version 6.3 (Build 9600).
Other computers on the local subnet can open the default website on each of the 3 hosts by entering each host's private IP address in a browser.
However, when I Port Forward port 80 on a gateway router in turn to each of the 3 hosts private IP address, then enter the public IP of the gateway router into a browser on a computer outside of the private network, only the Windows 7 host displays its default website.
When Port 80 is forwarded to either of the two Windows 8.1 Update hosts, the browser reports "This webpage is not available. Details: The host took too long to respond." Additionally, no record of the request appears in "C:\inetpub\logs\LogFiles\W3SVC1\u_exYYMMDD.log" on the host.
All three hosts have their Windows Firewall Inbound Rule "World Wide Web Services (HTTP Traffic-In)" set to Profile: All, Enabled: Yes, Action: Allow, Override: No, Program: System, Local Address: Any, Remote Address: Any, Protocol: TCP, Local Port: 80, Remote Port: Any, Authorized Users: Any, Authorized Computers: Any, Authorized Local Principles: Any, Local User Owner: Any, Application Package: Any.
Furthermore, disabling both Windows Firewall and Windows Defender made no difference. I have not installed any other security or firewall systems.
It appears that something is preventing port 80 requests from public ip addresses from reaching Windows 8.1 Update IIS. Yet the success on Windows 7 demonstrates that the gateway router is properly forwarding outside traffic to the assigned IP address.
What could be blocking the public ip port 80 requests to Windows 8.1 IIS, and how can I correct it?
Problem solved. It turned out the cause was Check Point VPN v98.60.202, from Check Point Software Technologies. I had installed this software to connect to a corporate client's internal network.
I suspected this was the cause because of how VPNs work, so I had previously closed the VPN software, but that didn't solve the problem. I actually needed to completely uninstall the Check Point VPN software and reboot the computer to remove the hooks it makes into the Operating System's TCP/IP stack. That allowed IP addresses outside of the host's subnet to again be served by IIS 8.5.

Accessing localhost website on LAN from VMware

Systems:
Windows Server 2008 R2
IIS 7.5
VMWare 10
i wanted to access the website hosted from other LAN machines.
Inside the machine there is a VMware 10 running windows server 2008 r2 and iis 7.5.
i set a bridged connection for the VM and using a static ip xxx.xxx.x.198 in windows server
I added a binding to my website (:122).
I added inbound and outbound rules in the firewall settings.
However, i managed to access the webpage from the host machine (windows 8) outside of the VM.
But i can't access the webpage from another machine.
Are you sure you've checked the firewall machines on both the guest and the host?

Connect to VM running on the same computer without LAN

I have a windows 2003 VM running on my windows xp machine.
The machine name of the VM is itdom.domain.com
The windows xp host machine is disconnected from the LAN.
I want to be able to connect to the VM from the host and vice versa using there computer names. For example the URL http://itlab.domain:7080/domainsm must be accessible from the host computer.
Is there any configuration that I can do on any of the machine to do this.
Just because you have no physical network connection doesn't stop you setting up networking on the host and guest machines. One way of doing this is to add an IP address to the host machine's physical network port and create a bridged network on that port so that the guest can also see it.
You don't say which VM technology you are using, but in many of them you can setup an internal network between the host and guest. All you need to do then is edit each hosts file to add a hostname for the IP address of the other machine. You may also need to configure firewalls to allow access between the two.
No doubt there are also other ways to achieve this.

Access localhost on the main machine from VMware Workstation 8 for ASP.NET development test

I run an ASP.NET Development Server (that came with MS Visual Studio 2010) on my Windows 7 machine. I'm currently developing an ASP.NET C# web application and to test it on Windows 7 machine I need to navigate my web browser to an address like this:
http://localhost:59215/Default.aspx
I also have the VMware Workstation 8 installed on that Windows 7 with other OS as virtual machines. I need to try to load my web app from those virtual machines, but when I type the above address there I get "Cannot display page" error in a browser. Note that I can access internet from a virtual machine itself, but for some reason localhost on the main machine is not accessible.
Any ideas how to set this up?
OK, I got it!
For those who're interested, here's how:
Say, my developement URL on the host computer is:
http://localhost:59215/Default.aspx
Download this util, called tcpTrace and run it on a host machine. When it starts configure it as follows:
Listen to port #: 80
Destination Server: localhost
Destination Port #: 59215 (which will be different in your case)
Click OK and let tcpTrace run on the host computer.
On the virtual machine navigate the browser to the IP address of the host computer, for instance in my case:
http://192.168.0.4/Default.aspx
and it will work!
PS. To get an IP address on the host machine, run ipconfig there (in a command prompt window). Your IP will be presented in the "IPv4 Address" line for network you're connected on.
PS2. Also my Windows 7 (host) doesn't come with any third-party anti-virus or firewall. It has a built-in Windows firewall and MS Security Essentials as an AVP. So if your setup is different one needs to open the incoming port 80.
PS3. Speaking of the VMWare Workstation, the virtual machine's network adapter setting is set on "NAT: Used to share the host's IP address" as it came out-of-box when you install it.
localhost is the local machine (to the OS).
I'm not sure if the VS dev server will allow external connections, you may want to install IIS - either way, you'll have to open up the Windows Firewall to allow external connections.
I'm no VMWare user but each OS will have its own IP address(?) - and that's how you'd connect to the Windows 7/IIS image. http://the.ip.address.of.the.win7.image/

can't ping SQL server or connect to SQL server when using server name

I have SQL server running on a legacy Windows 2003 box on IP address 192.168.2.240. There seems to be a reference to the server with some old connection strings for a web application. I'm merely using it for comparison purposes because we just upgraded to Windows Server 2008, .NET 4.0 and Enterprise Library 5.0. The server is referenced with "SQL01" not the IP address. On the network where this IP address resides, I can ping "SQL01", but when I VPN to that network, I cannot. Why wouldn't this work over a VPN? This is a legacy server, and I don't know how it was setup. If anyone can explain where this name is configured, and how I can connect (or ping) "SQL01" instead of using the IP address, I'd like to be enlightened.
Try looking in your hosts file.
