The error messages “ERROR: Login to remote object” or “ACCESS_DENIED” can occur when attempting to monitor Windows services using WMI or WBEM (in the Windows environment, these terms are used interchangeably). If you have ruled out the possibility that a username or password was not entered properly, there are two common causes for this error.
The most frequent cause is a result of too many requests accessing the WMI/WBEM service simultaneously. We have frequently seen this problem occur in conjunction with the McAfee NITRO agent during updates, but it can also be caused by high system load or other management applications accessing the server simultaneously. If the problem resolves itself after a short time, this is the likely cause.
If the problem persists, or you also receive “WMI: Generic error” messages, this can indicate that the WMI repository or other system files are corrupted.
Experienced administrators can see our page on Fixing WMI Corruption in a Windows Server for some advice on potential repairs.
