Please help me sorting this problem out as I am not sure what's caused it and how to resolve it. First off, our environment... Windows 2008 DC's single domain, and Windows 7 Professional clients via a bonded T-1 MPLS between the sites... a DC is located at each site. The problem is some time, most of the time...for a few users that it take them a while... some time up to 3 minutes to logon or open a file locally or from a file server at another site. Please advise. Thanks.
