We have approximately 75 Terminal Servers and whenever we
have a power cut the servers stay up but the network
switches go off-line temporarily and the servers loose
there connections. When the powers comes back on we find
that roaming profiles take a long time downloading and the
servers run very very slowly.. this is all fixed by re-
starting the servers - is there another solution? Like
stopping and starting some services?

Thanks for your help
 
Have you considered buying an UPS for your switches?
Are the sessions on the TS going into the "disconnect" state? Can you
configure a time limit on disconnected sessions? Or configure your
UPS-software on the servers to run a batch job that does this when
the power goes down?
 
Thanks for the response... however at this moment in time
we don't have enough in the budget to UPS our switches...
We currently have the idle and disconnected session set to
60mins each - however this still doesn't help... Even
after the power comes back on (or while the servers are
running on UPS) we log off all users on the TS and still
get problems next time they logon.

Thanks Again
 
Sounds to me that the problem is related to the servers loosing
their network connection, more then a problem with the sessions
(since I understand that you log those off anyway).

For exactly this reason we have configured our UPS management
software to wait for 5 minutes before booting up the servers
again, after the power comes back (if the power outage has lasted
so long that the UPS has shut down the servers). This makes sure
that all switches have gone through their self tests when the
power comes back, before the servers boot.

One work-around that comes to my mind in your situation is to
configure your UPS management software to reboot the servers when
the power comes back. Not a nice workaround, but since your users
are logged off anyway, it will only add some minutes to the time
that the servers are unavailable to them.
