Slow Application performance in "Domain" Network Location

[yanks2112]

Hello,

I have a Windows 7 PC, fully patched, that when is a memeber of a domain, a particular application runs extremely slow. If I remove it from the domain and use the private or work network location it runs great. If I use the public network is runs as slow as when it is in the Domain network location. The application runs locally but accesses network resources outside of my LAN

This is an older program that was custom built so unfortunately I cant upgrade it (I beleive it was written in VB). Has anyone noticed application performace suffering when a PC is using the Domain network location? I have tried disabling the firewall. I have added the site that the application is connecting to to the trusted Zone in IE. I've looked at different GPO settings including Applocker, but hve been unsuccessful. Any help would be appreciated

perhaps this is an issue where SMB2.0 conflicts with the OLDER software...

read the following, for testing and some info:

How to Disable SMB 2.0 on Windows Vista/2008

http://www.petri.co.il/how-to-disable-smb-2-on-windows-vista-or-server-2008.htm

I would also suggest that you check the DNS settings, make sure that the SERVER is set as the GATEWAY and not an InternetRouter...

Hi BigBadBen
Thanks for the reply. I made the change the article suggested but with no luck. I found an article which deals with Windows 7 runing slow on a network. The article suggeted that I change the Receive Window Auto Tuning Level to disabled using the netsh command and it worked!
The command is: netsh interface tcp set global autotuning=disabled

The article is here:

Thanks again!

glad you found the solution (would've been my next suggestion, just didn't have time, posted during work hours ;-) )...
