Yes, I did reset local admin password.Domain password did not change.Problem is occurring at few PCs not at all.Yes I did change it manually.Actually, when I try to print from the share printer then it ask to give user name and password.I give user name and password(old password,which is also domain password) daily and then it start to work properly whole the day.
Need to make sure the shares are setup properly. If you have 200 computers you really need to be using network accounts to setup rights not the local admin account. You don't want to be working with sorting out where the rights issue is coming from. It's tough to add every local account to a share without adding Everyone to the groups. Setup a generic user account if you like for every computer to use, add that account to the group that you give share and printer rights to.
