Hi,

This is the background of the problem.

Windows 2003 Servers running AD. 2 Servers, Primary and Backup.

2008 R2 servers are joined as members of 2003 AD. Mail server and File server

Clients - Win XP, Win 7.

Share folders on Fileservers were accessible from both type of clients.

Since windows update happend last week (12/03/2015),Win 7 users are being rejected by the 2008 servers

Win XP users do not face this issue

Please help, it's driving me nuts :)

Thanks

Thepul
