In our office all PC are connected in network using workgroup. But sometimes when we connect to a windows 7 shared folder from an Windows xp pc i get error like
\\pc123\myfolder is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Access is denied.
But if i restart the Windows 7 PC after getting this error then and retry to connect from windows xp PC then it connects properly. Also from other OS(windows 7 and 8) the pc can be accessed and no error comes anytime, even during the same time when error for windows xp pc came. So this error has no definite sequence to recreate the error. This is not problem with permission as i have full permission for that share. So what may be reason behind this?
