MSProxy Winsock DNS Problem

We have MSProxy 2.0 SP1, IIS4, internal and external DNS (key component).

We are having problems with DNS resolutions.

If the microsoft proxy client is installed, all dns queries go directly to the proxy server. If you remove the microsoft proxy client, the TCP/IP DNS entries are used. Is there any way to keep MS proxy client installed without MS Proxy Client from intercepting and redirecting my DNS queries from my internal DNS server to the proxy server, which also has our external DNS server on it?

Thanks,

Daniel

Is this information from TechNet relevant?

"The Microsoft Proxy Client will, by default, forward all FQDN name queries to
the proxy server on your network. The proxy server then forwards these queries
to its DNS server, which is most likely on the Internet. Unless your internal
domain name(s) are registered on the Internet, the name resolution for the
internal domain name will fail when processed by an external DNS.
Edit the Mspclnt.ini file to add your internal domain suffixes as described in
the Microsoft Proxy Client documentation using the LocalDomains entry.

Using a text editor, open the Mspclnt.ini file and add or edit the LocalDomains
entry in the [Common] section and set it equal to any domain suffixes that exist
on your internal network.

For example:

[Common]
LocalDomains = test.lab.com, lab.com"

I hope this helps.

Yes, this did help and solve the problem. I do not understand the first part of the message that you left, "Is this information from TechNet relevant?" Does that mean that that this message shouldn't be posted here or are you asking if I have read your message yet... If you possible could, please email me with the documentation location that you found this in. I have the documentation online, no manual was present at the time of the opening of the box.
