Windows Account - Slow Internet. Mac Account - Fast Internet

[Richie1972]

We're suddenly having a weird issue here and, not being in any way a mac expert, i have no idea how to fix it.

 

Our Setup:

Server 2008 R2 Domain

Apple XServe

Macs connected to Open Directory and Active Directory.

Macs and XServe on one VLAN, Windows servers on another

 

Up until yesterday everything worked fine.

However, now if you login with an Active Directory account internet access is really really slow (via all the proxy servers we have).

Straight away I thought this must be a DNS issue, but if you log in on the same mac with the local admin account (pointing to the same proxies) it works fine.

 

I've tried unbinding and rebinding to Active Directory - no difference

I've checked access via Windows computers using the same users and logins - no difference

 

What is the next option?

Are you using live or local home folders ?
