every time the PDC goes down, the bdc can't validate users even if i try to open usrmgr.exe or srvmgr.exe shows a error "can't access the domain". the event viewer shows
1.- Redirector has timeout a request to domian
2.- the pipe is invalid
3.- NT LM security support provider service terminated with service-specific error 3056

the NDS4NT is loaded on the BDC and PDC (becouse there are in diferents locations)
When i try to logon on to the domain a got the error "domain can not be found"

The BDC needs to be promoted to PDC when the PDC goes down it is not an automatic election. The BDC is meant to be a copy of the PDC logon files. In turn when the orginal PDC comes back up you bring it up as a BDC then demote the other one to BDC and promote the orginal back to PDC. You can not have two PDC at the same time. This should help.
Good Luck
