computer management

Hello

We upgraded our domain from W2K to W2K3 (domain controllers only,not AD
mode) and enabled RPC over http for Exchange recently. I am not sure if this
is related but thought it was worth mentioning.

We are having intermittent issues with conecting to windows servers via
Computer Management. The error is moft often access denied. The denied acces
error is not conistent to one or two servers. It is not even consistent with
Access tot he system. Sometimes the error is experienced when trying to
access Event Viewer, or Disk Mgt and ect..

Any thoughts would be greatly appreciated.
Thanks,

Mark
