Sage accounts 50 2011 major issues.

Hi, I wonder if someone could help please

Clients network consists of SBS2011 some xp machines and one Win 7 box

when the XP machines are just using sage everything is fine. However when the Win 7 box starts using sage it freezes the network for everyone.

I've managed to get a half resolution by disabling both SMB2 and Oplocks on the server and then Windows 7 client.

I say half as everything was running fine for about two hours and then all of a sudden the same problem again.

Any advice please ?

Thanks in advance
