I have an error on my Exchange Server 2007 that has been coming up every night at the same time. I'm concern cause I have been experiencing issues with new user's Outlook syncing up with my Exchange Server. How can I fix this issue and is this something that could prevent new users Outlook from syncing with Exchange Server.

Publishing the Key Management Service (KMS) to DNS in the 'RAPA.local' domain failed.

Do you have a record in your DNS under _tcp branch of type _VLMCS ?


On my DNS server which is my DC (Fileserver2) has VLMCS as my Citrix server not my Fileserver2 which again is my DC and DNS. Is it supposed to be that way?
Yes your KMS server does not need to be a AD/DNS server - to fix your problem:

To automatically publish KMS in additional DNS domains
On the KMS host (this seems to be your Citrix server as you state above), create the following registry key:
KLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SLValue Name:
DnsDomainPublishList Type: REG_MULTI_SZValue Data: Enter each DNS Domain
that KMS should publish to on separate lines.

I thought my KMS server was my AD DC/DNS server (Fileserver2). How do I determine which server it's supposed to be?
