The subject behavior can be the result of the not having the PnP ISA Enabler started or having some files in %SystemRoot%\System32 missing or corrupt.
To fix the problem, verify that the PnP ISA Enabler is configured:
1. Navigate to <CD-ROM:>\DRVLIB\PNPISA\<Your Platform>\PNPISA.INF.
2. Right click and choose Install.
3. Restart your computer.
If any of the following files are missing from %SystemRoot%\System32, reapply your latest Service Pack:
Shell32.dll Rpcrt4.dll Tapi32.dll Setupapi.dll Msvcrt.dll Lz32.dll Comdlg32.dll Version.dll Cfgmgr32.dll Mpr.dll Rpcltc1.dllNOTE: PNPISA is a "use at your own risk" tool, since Plug and Play devices are not supported in Windows NT 4.0.
