After adding Win7 PC to domain, one certain website is very slow to access

I have a client with a standard Windows 2003 server/network.  Just deploying some new PCs, with Windows 7.  

They use a specialized website that they use for client tracking.  This is the situation:

- on a regular XP PC, connected to the domain, they can access this particular website no issue.
- on a new Win7 PC, before the computer is added to the domain, no issues with access or speed
- when we add the Win 7 PC to the domain, this particular website slows down considerably.  e.g. something that took 1 second before, now takes 40.

It is specific to adding the computer to the domain.  It does not have anything to do with:
- account you login with
- Addons with IE
- Proxies

Unfortunately, this particular website does not allow Firefox nor Opera, it must use IE.

Any helpful advice appreciated,

Is this an internal website, i.e. it's hosted internally on the same network?

In what zone does the browser load the website? Internet, Local Intranet, Trusted Sites?

Have you tried adding this site to Trusted Sites and see if that makes any difference?

Thank you!

This is an external website.
Adding to Trusted sites makes no difference.

Thanks for the input on this.

Do you use IPv6 on your network?  If not, disable it in Win 7 and check again.

I disabled IPv6, but no difference.  Thanks for the input, though...

Just to re-iterate: before putting the computer on the domain, all is fine.  Nothing, except the act of putting the computer on the domain, has changed.  All network settings, etc. remain the same.

Do you have any GPOs which affect firewall or network settings?  On Windows 7, can you do a GPRESULT with the verbose switch?
  • GPRESULT /V /SCOPE COMPUTER (has to be done from an administrative CMD prompt if UAC is enabled)
Please post the results.

We ended up installing the XP Virtual Machine, and that worked great.  The site that was causing the trouble is being replaced in a couple of months, so we aren't pursuing this any further.

Thanks for your time on this.
