Error 0x800704b3 when trying to map a network drive

Hi there,

I have the following error when trying to map a network drive in my home network:
iomegahmd can not be reached" and the error code is 0x800704b3.

I already looked into the services, and my strong assumption is that the problem is that the service "TCP/IP NetBIOS Helper" is not statrted and it is disabled. When I try to start it, there is an error message:
"The system could not find the path specified".

I've also checked the dependency components of the service "TCP/IP NetBIOS Helper":
Ancillary Function Driver for Winsock
TCP/IP-Protocol driver
NetIO-Legacy-TDI Support driver
in the device manager if they are running, but they are all running. The start is set to "System".

Under the TCP/IP Internet version 4 properties of the wireless device, under Advanced -> WINS I’ve set „Enable NetBIOS over TCP/IP“, but it didn’t help either.

What else could I try, so that I can map network drives?

I should also mention, that the problem persist since some week ago. Before it, it was properly functioning. Also, on the other computers in my networks I do not have problem accessing the same network drive.

Thanks in advance,
Problem solved by myself. By comparing the registry entries under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\lmhosts with other PC where it works, I just modifed the value of "Start" from 4 to 2, which means automatic start of the service TCP/IP-NetBIOS-Hilfsdienst.
After rebooting - it worked!

Good luck to all the other readers with the same problem,
