Q. After installing eScan, I am unable to browse the Network Neighbourhood! What could be wrong?
A. Run regedit.exe, Goto
HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Services\\LanmanServer\\Parameters
Set the value of
IRPStackSize (DWORD) to 12 (hexadecimal 0x0C).
After the setting is done, reboot your machine. This should solve your problem.
