RE: Migrating W2K3 to W2K3 server?

["Paul Gale" <groups@xxxxxxxxxxxxxxxx>]

With my problem though - it wasn't slow transfers that is the problem
- it looks like it's actually losing the connection altogether. Although,
when I try browsing the network straight after, it seems to be working fine
- maybe a temporary loss and then restores itself?
