Problem with Users Accounts
Posted on 2011-04-28
Hi guys, I've been experiencing a problem with some of my user accounts over the past 10days or so. Initially, I thought it was an isolated situation however, the problem had repeated itself severally in the past days and I'm beginning to wonder what might be wrong.
Here is the problem:
Some of my users just suddenly start experiencing identity related issues after signing on to their PCs. The incidents includes - MS Outlook and Internet Explorer pops a login window when started. When they try to access a network location they receive a window also asking them to logon. Sometimes this problem goes away in a few minutes such that by the time a support staff gets to the user's desk, the problem is no longer there. However, when the problem persists, support staffs usually do either or both of the following to resolve it: remove the affected PC from the domain, restart it and join it back to the domain OR log the user out, delete the User's account from Active Directory users and computers MMC console, recreate the user account. However, this still doesn't prevent the problem from occurring a day or two later with the same user account.
In addition, some of the other PC's name on the domain suddenly changes. This happens only on Windows 7 PCs though. For example, say a Windows 7 PC that was a domain member which was originally named Stev07 suddenly changes name the next morning to HP-USER!
NB: When I check the log on by ISA Server, I notice that when IE start demanding a login, the requests are logged for Anonymouse users anonymous Internet access is not permitted on this network!
What do you think might be wrong here please? Kindly bail me out of this one guys.
I run a network spread across two locations linked by Microwave Radios (I'd call them location A and location B respectively)
Location A has two Domain controllers (I'd call them DC1 and DC2), which are both Windows Server 2003 boxes. DC2 also host Exchange 2003 (I know this is not recommended only learnt this after the action and since it didn't seem to be an issue, left it alone). Most of the PCs in Location A are Windows XP Pro PCs and point at DC1 as the primary DNS and DCs 2 and 3 as Secondary and Tertiary DNS respectively
Location B has a domain controller DC3 which runs Windows Server 2008. Most of the PCs in Location B are Windows 7 Pro PCs. All PCs in Loc B point to DC3 as the Primary DNS server and DCs 1 and 2 as their Secondary and Tertiary DNS servers respectively.
All PCs and Servers are shutdown at the close of work
