Quick question: are the source and target accounts' passwords the same in all cases? If so, try setting different passwords and do your tests again. Sincerely,

If i'm on a target pc trying to access a target server with a source account, no go. If i'm on a target DC trying to access a target server with a target account, all is good. If i'm on a target DC trying to access a target server with a source account, all is good. If i'm on a source DC trying to access a target server with a target account, all is good. If i'm on a source DC trying to access a target server with a source account, no go. Hope that helps a little. Thanks On 2/22/06, Tom Kern <[EMAIL PROTECTED]> wrote: We migrated inter forest. We are still coexisting with the source forest. This company still stages and deploys machines and users in the source and then migrates to target. I know this is a really bad practice but I can't talk management out of it. So, in summary, when i'm on a migrated box and i try to net use to a share with a target account i'm fine. If i try to net use from a migtrated box with an account still in the source, i get "Logon Failure: The target account name is incorrect". This always worked until yesterday. DNS is working and it resloves to the correct domain when querying a flat name. In a packet sniffer while net use'ing with a source account i get a bunch of Kerberos errors. If a net use with a target account, I get different Kerberos errors and the auth fails over to NTLM and i get in. The SPN's look fine to me. If i'm on a migrated box in the target and the source "copy" of that box had its password expire in the source Forest, would that affect me? Then I wouldn't be able to log in at all. If quest sync's password expiration of machines from source to target, no one would be able to log on to any domain. are there any issues with leaving a copy of source objects and sync'ing changes from source to target?

Now you are trying to log into source from an already migrated computer. Right? Could your problem be because the computer's password has expired on the source domain? I'm assuming that you did an inter-forest migration which left the computer account in the source after the migration. btw, what are you still synching with the Quest tool if you've already migrated everyone?

Thats the question. Here's more of the story as i'm learning- i only get these errors when auth'ing with an account in the source forest. using an account in the target forest seems to work ok. most of the servers are in the target forest now. The workstations are spread over both. i verified the trust and its up and working. we have been in this state for 4 months with no issues until today and there have been no migrations in about a month of any sort. the only thing running is the quest sync agent which sync's source to target(no deletions).

I ran Ethereal will mapping a drive, both ways. With the flat name and fqdn. When mapping with the flat name, I see a "KRB5KDC_ERR_PREAUTH_FAILED(24)" Then later, I see, "KRB5KRB_AP_ERR_MODIFIED,Error: STATUS_MORE_PROCESSING_REQUIRED(0x0000016)" When I use FQDN, I see- "KRB5KDC_ERR_S_PRINCIPAL_UNKNOWN(7)" and then it defaults to NTLM and lets me in. With a flat name, it never gets to NTLM. I've checked the "Troubleshooting Kerberos Errors" MS whitepaper but I can't find anything to help me there. The SPN in AD of my box and the server I'm connecting to seems find. Both client and server are in the same Domain. DNS is functioning. Time is in sync. Anyplace else I should be looking? Thanks a lot.

I've noticed we've had many login issues where users can map drives via ip but not hostname(dns is working and you can ping by name). Also, when connecting via a drive mapping, the error recieved is "Login failure: The target name is incorrect". Now I know when mapping via ip, you are using NTLM as opposed to Kerberos when you use a hostname. So I thought it was a duplicate SPN issue due to the migration. When I fire up LDP.exe and search for SPN, I see the pc in question has an SPN of the value "host\pc.Old.Domain.Name". There is no SPN for the pc to reflect the new Forest it has been migrated to. This is sporadic and doesn't affect all migrated pc's. Another symptom is users not getting their home drive mappings(via ADUC). The homedir server logs this error in the Security log- Event Type: Failure Audit Event Source: Security Event Category: Logon/Logoff Event ID: 537 Date: 2/21/2006 Time: 11:16:05 AM User: NT AUTHORITY\SYSTEM Computer: OPNJR01 Description: Logon Failure: Reason: An unexpected error occurred during logon User Name: Domain: Logon Type: 3 Logon Process: Kerberos Authentication Package: Kerberos Workstation Name: - I have two questions- 1. Could the issues I'm having be a symptom of this SPN "problem"? 2. Has anyone faced a simillar issue when migrating either via Quest ot ADMT,etc? Thanks a lot.
