Recently we migrated a client's Server 2003 domain controller to Server 2012 R2. That migration included roaming user profiles. The profiles were copied from the 2003 machine to the 2012 machine using Microsoft SyncToy. Subsequently, we used AD to map the user accounts to the profiles on the 2012 server.
Here's the roaming profile environment:
User profiles are mapped to \\SERVER\profiles$\%USERNAME%
User Home Folders connect X: to \\SERVER\Userdata$\%USERNAME%
Using Group Policy, the Desktop, Documents, Pictures, Music, and Videos folders are redirected to \\SERVER\Userdata$\%USERNAME%\
I'm only assuming that these issue are related to roaming profiles, but here are the symptoms (Windows 7):
Internet Explorer (11) takes 20-30 seconds to open. Opening new tabs in IE takes as long. Otherwise, IE functions normally.
The Services.msc console (and I assume other MSC consoles) takes 20-30 seconds to open
Searching from the Start menu takes a very long time
We're really pulling our hair out trying to figure out these issues. Any help is greatly appreciated. I can provide any additional info you need.
