From McAfee's website:
Solution 2 - Troubleshooting issues
with a UNC repository
Click Start, Run, type the full UNC path in the format below and press
ENTER.
\servername\sharedfolder\
2.
Confirm the following files are present:
3.
*
SiteStat.xml
*
catalog.z
*
Current (folder)
NOTE: If the folder opens but these files are missing, the issue
lies with the process or application
that is responsible for populating
this repository. If the folder does
not open, the repository may not exist
or the logged on user may not have the
correct read permissions to access the
share.
To set the Permissions:
1.
Open the VirusScan Console:
For VirusScan Enterprise 8.5i, click Start, Programs, McAfee,
VirusScan Console
For VirusScan Enterprise 8.0i, click Start, Programs, Network
Associates, VirusScan Console
2.
Select Tools, Edit AutoUpdate Repository List.
3. Select the appropriate repository from the list, then click
Edit.
4.
Ensure that the UNC path is correct.
5.
The Use logged-on user box can be selected if the update will be
taking place when a user is logged on
to the computer and the user has the
correct permissions.
If reliance on a logged on user is not appropriate, then the box
should be deselected and a user
account with the correct permissions
should be typed.
