RE: systems can not find local DC

Hello Leke,

AS you can see in the output GCOMLDC isn't able to replicate with GCOMLFPS:

[Replications Check,GCOMLDC] A recent replication attempt failed:
From GCOMLFPS to GCOMLDC
The failure occurred at 2010-06-15 13:46:34.
The last success occurred at 2007-06-21 16:40:50.

So how many DCs are avaiable now and in total and please post the names so
we can get an overview.

Best regards

Meinolf Weber
