We recently needed to down our servers ??? 2003 R2 SBS & file server 2003 R2. The file server (also a domain controller) was downed for some time and then lost its NIC which we replaced after removing the dead NICs drivers. The file server is up and running but since then:
1. We get Access denied when attempting to RDP to the file server. The file system & shares are available on the network ??? we just can???t remote desktop to it. The file server (not SBS/exchange server) has Kerberos Errors:
KRB_AP_ERR_MODIFIED error from the server host/sbs01.abc.local. The target name used was DNS/sbs01.abc.local.
KRB_AP_ERR_MODIFIED error from the server host/sbs01.abc.local. The target name used was exchangeMDB/sbs01.abc.local
No passwords were changed on either server. The SBS domain controller has replication errors which we expected whilst the file server (alternate domain controller) was out of action. RDP to the SBS works perfectly.
2. Outlook shows Exchange (on the SBS) as offline although the MS-Exchange store is mounted & no errors on info store or Exchange startup or event viewer. On the same PCs that Outlook show Exchange as being offline, we can use OWA to access the users mailbox, proving the info store is accessible.
Does Active Directory or DNS keeps a record of the NIC hardware that was replaced, which is causing these problems problem or whether it???s because ADs on both servers failed replication beyond the tombstone period?
I???m wondering whether these problems are related and best resolution steps.
