Strange Network Issue

[gchildX]

Hi guys,

I wonder if I might be able to pick your brains on a subject that's got me totally lost.

We've got a single PC on our network that has a sporadic issue (every 2 or 3 days)

When the user boots it up in the morning it starts normally, logs into our network normally, but when it attempts to connect to the mapped drives it comes up with System Error 1231, ERROR_NETWORK_UNREACHABLE.

When we browse into the Windows Network we can see the domain, but when we go into it, it's empty.

The connection light is still on, on the NIC. (first thought was bad cable) But when it's doing this, the user can still check email and load webpages.

After a few reboots it will suddenly start working again.

All the policies look normal, I'm at a complete loss as to what could be causing this issue.

Anybody have any ideas?

Thanks,

G.

Hi JP,

Thanks for the response, unfortunately that was one of the things I checked out first. That issue only applies if there are 15 or more DC's in the domain and we only have 3.

I searched the net and Microsoft and couldn't find anything that applies to the situation.

Any other ideas?

G.

What are you using for name resolution?

The domain being empty in network neighborhood is a sign of master browser problems.

Drives not mapping are likely other name resolution issues. When you are unable to map can you do nslookups or anything?
