Unable to access networked drive, but able to access same unc path

[PUD-02]

I have a Western Digital My Book (World Edition) connected via nic to
wireless router. Have previously had no issues with mapped network drived
till i reformatted and reinstalled xp to my laptop. (Previously running xp).
system is exactly the same... only difference is that I have gone from AVG
Free antivirus to ESET Smart Security. I can map my network drived to the My
Book, all others work appart from one. But I can access the unc path without
issues.

Please help... going Grey and pulling out hair!!

Hi
If the network IP changed and the Firewall changed it could be that the
current I is Not anymore in the Trusted zone and block sharing.
It should be readjusted (read the ESET manual).
General example, http://www.ezlan.net/faq#trusted
Make sure that the Software Firewall on each computer allows free local
traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should
be Off, and the active Firewall has to adjusted to your Network IP numbers
on what is some time called the Trusted Zone (consult your 3rd Party
Firewall instructions.

But the strange thing is that I have other mapped drives to the same device
and they work absolutely fine, it is just the one particular mapped drive. I
have assigned a static IP to the device. The IP range has been added to the
trusted zone. Also I have checked and re-checked the permissions on the
shared folder. I have a 2003 server which has no issues accessing the same
mapped drive. It has the same ESET antivirus and firewall installed.

PS: Extra hair loss!
