i have 3 Dell R610 servers with MS Server 2003 SP2 overseas that now have black screens when trying to RDP to the server after we've installed MS patches. the techs in the field say that the servers are usable (ie print server functionality and shares are accessible) but neither i or regional techs can connect to the servers via RDP to check event logs, required maintenance, etc. rebooting the machines has proven a temporary fix for this issue in the past, but will result in a black screen again the next day many times. that type of event has been intermitent. i am of course hesitant to reboot these servers as they are being used at this time. of course i understand a patch could have messed up the RDP process, but i've had this issue in the past not related to MS patches as well. i guess i have 2 questions:
* what could be a cause/fix for this happening intermittently at times before this? i understand there may be multi possibilities - feel free to tell me this is difficult to diagnose off my information if this is so.
* what would be the best process to fix the black screen that happened after the patches?
