Currently: Netware 6.5 SP8
Workstations: WinXP SP2
Client: 4.91 SP2 and SP4

I have enabled "Automatic Update Agent" with all settings set and
pointing the update location to our intranet website where I have the
latest client "4.91 SP5" files, in the Novell Client for Windows
properties

If I manually run the update check by right clicking on the red N and
clicking on "Update Novell Client" I get the following message

"No update to the Novell Client for Windows could be found."

If I copy the latest client files to a local folder on the computer and
change the update location in the novell client properties then run the
manual update again, the client tells me that there is an update

"An update to the Novell Client for Windows is available
Currently installed: Novell Client for Windows 4.91 SP2
New version: Novell Client 4.91 SP5 for Windows
Would you like to install the update"

If I copy the latest client files to a mapped netware volume folder on
our network and change the update location in the novell client
properties then run the manual update again, I get the same issue as
the first one

"No update to the Novell Client for Windows could be found."

How can I get the update to work?
Why does it only work if the client files are on the local folder?

I have even re-downloaded the latest client files from Novell and made
no changes and I still get the same problem if the client files are on
the intranet for netware volume

Please help
Thanks in advance
