Event InformationInformation from a newsgroup post for the Error: "Cannot find perfmon object in array returned by perfDLL, index=4" 
"I had been troubled by the same error for a long while, and recently I finally found out the cause and got it fixed. It turned out that for some reason the performance counters in "PerfOS.DLL" were disabled. Once they were enabled, vmauthd has no problem to retrieve those "perfmon" objects it needs, and the error goes away. To see whether your performance counters in "PerfOS.DLL" are disabled, you will need a program called Extensible Performance Counter List (exctrlst.exe). It can be found in the Support Tools folder on Windows XP Pro CD, or the Windows 2000 Resource Kit CD. If you dont have the proper CD, you can download it from Microsoft, just follow the link below. After you install the program, run it and set the "Sort Order" to "Counter ID". You should see "PerfOS" near the top of the list. Click on it, and its status will be displayed at the bottom part of the dialog window. If the "Performance Counters Enabled" checkbox is unchecked, that means your PerfOS counters are disabled. You can simply check the box and press the "Refresh" button. Now start or restart your "VMware Authorization Service", and watch the "Application Event Log" to see whether the vmauthd error stops".

Another post suggest as follows: Description: "Error 1326 authenticating user <user ID>" - This error stands for "Logon failure : unknown username or bad password".
