I have a single domain network that connect three offices (let say A, B and C). A PDC and a BDC are installed on at the head office (A) and one BDC on each branch office (B and C).
People can logon no problem. But the weird thing is they have intermittent browsing problem. For example, some people in B can browse the resource at A and can browse others with their network neighbourhood. Some others just simply can't. I checked the Server Manager and the Network Neighbourhood from both the PDC and the BDC at A, I can see all the connected computers, including the troubled ones. When I tried to browse the troubled computers (either using Network Neighbourhood or net view or net use), they gave me error (Error 53, Network Path Not Found).
All people on Network B are connected to one hub and router.
Same thing on Network C.
I can successfully ping and traceroute all the computers.
My question is:
1. Why and how this can be happening?
2. Why only part can browse and others can't?
3. How to remedy the problem?
I've searched through the web, but can't find any answers.
