PerfMon, Run Remotely, Fails to Show all Logical Drive Instances (138853)
The information in this article applies to:
- Microsoft Windows NT Workstation 3.5
- Microsoft Windows NT Server 3.5
This article was previously published under Q138853 SYMPTOMS
When you connect to a Windows NT 3.5 computer remotely using Performance
Monitor (PERFMON.EXE), the number of Physical and Logical Disk instances
may be incorrect. One or more NTFS drives may be missing from the instance
list returned. This problem does not occur on systems with only FAT drives.
CAUSE
When you connect to another system over the network, Performance Monitor
connects to the HKEY_Performance_Data registry key, which is handled by
Winlogon.exe. In Windows NT 3.5, Winlogon does not correctly impersonat
the user connecting to performance registry key. Even though the user
running Performance Monitor has the correct permissions to see the root of
NTFS drive, that is, the user could connect to the root directory and view
the directory remotely, Performance Monitor fails to return the drive
instance and its performance counters.
Winlogon uses the default accounts of the administrators group, domain
users group and Everyone. If none of these groups have read permissions to
the root of a drive, Performance Monitor fails to return the drive
instance.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5.
This problem was corrected in Windows NT Workstation or Server version 4.0.
