>I have a home network with several computers running different op systems -

>The unit (notebook) running XP MC can see and access all network

>Other conditions:
>-XP MC unit can be accessed by all other units when it is started in safe
>mode with networking
>-This is a new condition.  XP MC unit shares were accessible to other
>network computers up until a couple weeks ago.
>-All units are in the same workgroup
>-All other units have full connectivity to each other
>-XP MC unit runs McAfee VirusScan Enterprise, but ran it for months before
>this condition existed.
>-No other unit can successfully ping the XP MC unit
>-When trying to access XP MX shares from a list of workgroup computers, user
>gets error that "\\[computername] is not accessible.  You might not have
>permission.....find out if you have permissions.  Network path not found" 
>-Condition exits whether XP MC unit connected to network via wired or wireless
>-No new software has been installed since before this condition existed

>Attempted remedies thus far:
>-Ran network setup wizard several times on all units
>-Tried with Windows firewall both on and off on all units
>-Tried with McAfee disabled
>-With task manager, ended processes running in normal mode to try and find
>one causing this condition
>-Tried to restore to a point when unit was accessible to LAN, but windows
>could not restore (after going through "all the motions" as if it were
>restoring successfully).  Note:  System restore working properly - I ran a
