Forest problem

[dangy]

I have one forest ant 2 child domains. The problem is that when clied domains dc starts they say that

Active Directory attempted to communicate with the following global catalog and the attempts were unsuccessful.

Global catalog:

\\bim.mslab.inf.elte.hu

The operation in progress might be unable to continue. Active Directory will use the domain controller locator to try to find an available global catalog server.

Additional Data

Error value:

1908 Could not find the domain controller for this domain.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

This event viewer is logged three times because there are 3 global catalogs. I try to ping them from that computer and anything is OK. All DC are in the same site (the forest has 2 DC and another 2 DC for child domains and 3 are global catalog)

Does anybody know how can i get out of this?

Best regards!
