Network consists of :-
1 Windows 2003 small business server
several laptop computers running XP pro or home
several desktop computers running XP pro or home.
Server set as Domain controller but not logging onto domain from workstations or laptops just using workgroup.
My problem is this :-
Every now and then about twice per day at random times the network stops.
If you are on a pc you are kicked out of network shares and you can not see an computer or file on the network.
On the server you can not see and workstation or shared folder.
After about 10 minutes it generally comes back on or sometimes we have to reboot the lot.
What I have done so far.
I have replaced the network hubs for switches but this has made no difference.
If you are on a workstation you can see no other machine same on the server so I am a bit lost as to what it is.
I would have thought if it was server specific then the workstations would be able to see each other even if they could not see the server.
Any ideas anyone this is doing my head in.
