lost connectivity over weekend

-

we seem have lost not connectivity between 3 offices connected via mpls wan link on weekend.

symptoms follows: office 1 can connect office 2 , office 3 resources without issue. office 2 , 3 can connect each other without issue, and to office 1 resources (i.e. internal shares on ftp server) cannot connect other network shares, nor rdp servers directly.

all resources respond ping fqdn offices.

interestingly enough office 2 resources not "available" can "made" available win 7 x64 client connecting network share using ip address. once has been done, shares are available via fqdn , netbios name. also, after connecting share, rdp connection works win 7 x64 client. above steps not restore connectivity when performed on xp sp3 client however.

the wan link has been checked , pronounced sound service provider.

nothing has been changed on infrastructure on weekend.

ideas?

 

"all resources respond ping fqdn offices."

when try connect share from xp machine error message? error message when try rdp?
