Actually problem started when backup team failed to take the backup of one server...backup fails while in the process of taking the backup of one file which is of size 70 GB..backup was being taken on the backup media...(Error it gave was insufficient system resources exist to complete the requested service)
When we (windows )team tried to logon to the same server with our credentials then it gave me error(Windows cannot load the user's profile but has logged you on with the default profile for the system. ,DETAIL - Insufficient system resources exist to complete the requested service)
That is why i doubted This issue is ceretainly related to the windows ....
Description of the server is 4 GB RAM,Xeon processor with 2.20 Ghz with virtual memeory 7-8 GB whereas recommended is 6 GB..
