I use an older version of the Wingate Client on my network.
Microsoft recently updated the Windows XP Update Process/Client and now it fails work properly giving an error code which is well documented but not specifically for Wingate issues.
Dispite WGIC not working, if I disable it and set Iexplorer to use the Wingate WWW.Proxy server instead, Windows Update works fine.
Can anybody suggest a reason why WGIC suddenly wont work with the new Windows Update Process/Client?
