Hi,
I have a strange question to ask. We have an RDS farm consisting of 20+ servers, in front of this is 2 dedicated redirectors that query the session broker. The two redirectors have been running fine for months and were created based on Microsoft Whitepaper"configuring dedicated redirectors for RDS farm"
This morning had a panic as nobody could log into RDS. The reason was because the two dedicated redirectors had somehow switched into "Drain" mode. I can confirm nobody had logged into those two servers and physically changed the logon mode. The
event logs show errors from 21:00 last night refusing logons becuase server was in drain mode.
So my question - Is it possible for a Win2k8 server to place itself in "Drain" mode? If it is possible then what would cause the server to change logon modes i.e. high cpu, stopped service, etc.
Other than the usual event logs is there any other log files we can browse that may indicate what happened last night when the servers were placed in "Drain" mode?
Any help on this would be much appreciated, as we would like to get to the bottom of this in case it happens again.
Regards,
Scott S.
