After a log file from 3rd party software took all remaining space on the C drive (20GB log file since removed). Administrator account is not functioning properly. when opening active directory or exchange System manager I recieve the error C0070002 ("The system cannot find the file specifed" facility win32 exchange system manager) I have seen that another person had the error and adding another user to the domain admins group solved thier problem (http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_21739617.html
If I try and modify a user to add to the domain admins group I get the error:
Snapin Error "MMC has detected an error in a snap-in. It is recommended that you shut down and restart MMC.
Report this error to Microsoft, and then shutdown MMC. (sends me to a 404 web page on microsoft)
Ignore this error and continue running (does nothing)
I also am unable to add an additional account.
Through the add user wizard I get the error:
The wizard could not successfully configure this user account. The following could not be completed:
-A home folder could not be created for this user.
-Quota information could not be set.
Do you want to keep this user account (yes/No) "answering Yes does not keep account"
To make matters worse administrator now logs in with a blank password. making security less then effective.
Any help would be much appreciated.
