Hiding the C: drive from Users

By pweathersby ·
Is there a way to hide JUST the C: drive from typical users on Windows NT 4.0 computers. These computers are configured with a 2GB C: partition and a 10GB partition with other multiple mapped drives. I wish to hide only the C: drive without hiding any other drives. I have reviewed both Tweak UI and policy settings and neither seems to work the way I want. Any other successful options would be most helpful.

Cont.

Warning: This value entry does not affect File Manager (Winfile.exe). Drives that you hide by using this value entry still appear in and are accessible from File Manager.

A thrid-party tool may do what you need. If you are using a management tool for the desktops, look into the docs for that. I believe Tivoli will allow you to do what you want.

Answers 2 and 5 are quite correct. The "NoDrives" value is what you want. First bit is Zdrive, last bit is Adrive when viewed in binary.
The specific value you asked for would be
00000000000000000000000100(binary) or 4(decimal) which hides only the C drive.
You can modify the admin.adm policy file to include this policy. It already exists in the template as 67108863(decimal) which hides all drives. If you were to simply change that number in the .adm file (with a valid number) your policy would work accordingly.

It's very workable. Start with 26 0's, simply replace 1's into the 26 bit binary value to fit your needs, convert it to decimal and use in the .adm file. (Or manually edit the reg... whichever works better for you)
If you're using a kixtart login script you can even write that reg value in straight from your script instead of using policies.

It is possible to hide all drives or just selected ones.

The value of 'NoDrives' defines which drives are visible. The low order (right most) bit is drive A: while the 26th bit is Drive Z: To hide a drive, turn on it's bit.

If your not happy working in Hex, add these decimal numbers to hide the drive(s):

A: 1, B: 2, C: 4, 8, E: 16, F: 32, G: 64, H: 128, I: 256, J: 512, K: 1024, L: 2048, M: 4096, N: 8192, O: 16384, P: 32768, Q: 65536, R: 131072, S: 262144, T: 524288, U: 1048576, V: 2097152, W: 4194304, X: 8388608, Y: 16777216, Z: 33554432, ALL: 67108863

Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
Value Name: NoDrives
Data Type: REG_DWORD

It is not recommended to play with registry..
