I have recently just upgraded our 2003 domain to 2008 R2. Everything was fine before hand.
However, after the upgrade, I have a single 2000 member server which is being difficult. This is what is happening:
1) Connections to the shares on the Server 2000 via IP address are slow, and timeout when scripts are used, and occasionally machines will not connect to the share.
2) Connections to the same shares via DNS work perfectly
3) Non-Domain machines are unable to connect to the shares at all.
Everything was fine before I did the upgrade, and extremely puzzled as to why this would have changed. Any help will be appreciated.
