Exchange 2003

[faza]

I have a Exchange 2003 and i have a series of errors which are constant throughout the day every 2 minutes in the Application log.

 

Error Code - 8213

Couldn't find an accessible writable domain controller for domain 'CN=Configuration,DC=DOAMIN,DC=DOMAIN'. DC=DOMAIN,DC=DOMAIN

 

AND...

 

Error Code - 8026

LDAP Bind was unsuccessful on directory MAGRAT.ADMIN.HODGEHILL for distinguished name ''. Directory returned error:[0x51] Server Down. DC=ADMIN,DC=HODGEHILL

 

AND..

 

Error Code - 8250

The Win32 API call 'DsGetDCNameW' returned error code [0x54b] The specified domain either does not exist or could not be contacted. The service could not be initialized. Make sure that the operating system was installed properly.

 

These three errors are constant throughout the day causing the exchange server to lose connection intermittently.

You have DNS configuration issues.

 

from a command prompt run nslookup on all your DC's

 

You MUST be resolving YOUR OWN M$ DNS server

 

If you have ANY errors running this command then you need to fix your dns.

 

90% of AD errors come back to failed or failing DNS configs.

Do a DCDIAG and see what the results are.

When you installed your Exchange Server, did you run ForestPrep and DomainPrep first?
