first lemme give ya some information about NTVDM
Process Name: Windows 16-bit Virtual Machine
Description: Application that provides an environment for a 16-bit process to execute on a 32-bit platform.
Company: Microsoft Corporation
System Process: Yes
Security Risk ( Virus/Trojan/Worm/Adware/Spyware ): No
Common Errors: N/A
Usually all 16 bit programs share the same session of ntvdm.exe and thus, share the same memory.
Try creating a shortcut to the program.i.e "Cyberroam Server Client" Go into the properties of the shortcut and make sure "run in seperate memory space" box is checked . This will force a seperate session of ntvdm.exe in memory .
If u are usin Windows Xp . then go to the properties dialog and then try changing the compatibility of the program i.e try to run in win 95/win me etc .
You may also try to setting the following registry value to
0.
HKLM\SYSTEM\ControlSet001\Control\FileSystem \NtfsDisable8dot3NameCreation
Hope this helps
