30 Day Application Log Freak Out

[mpapier]

Hello,

If I do not manually reboot my Exchange Server (Win2k3) for thirty days, the following appears in my application log, forcing me to reboot the server. Upon reboot, all is well (for thirty days). I will implement a scheduled task to reboot the server every week, to keep this from catching me off guard, but I'd like to understand what's happening...

1. Event ID: 9143
Category: RFR Interface
Source: MSExchangeSA
Description: Referral Interface cannot contact any Global Catalog that supports the NSPI Service. Clients making RFR requests will fail to connect until a Global Catalog becomes available again. After a Domain Controller is promoted to a Global Catalog, it must be rebooted to support MAPI Clients.

2. Event ID: 9074
Category: RFR Interface

Description: The Directory Service Referral interface failed to service a client request. RFRI is returning the error code:[0x3f0].

Please check whether the local computer is a member of the group. If it is not, stop all the Microsoft Exchange services, add the local computer into the group manually and restart all the services.

6. Event ID: 8026

7.Event ID: 2104
Category: Topology

Description: Process STORE.EXE (PID=4348). All the DS Servers in domain are not responding.

Any help/ideas would be greatly appreciated.

What's up with your GC? Exchange gets cranky when it can't find one and spits up stuff like 8007203a (ERROR_DS_SERVER_DOWN).

 

[mpapier]

I believe it is its own GC

Reboot - should fix the nspi problem
After everything comes up check DNS for the SRV records. If they're not there - restart netlogon service.


Many times when a DC/GC points to itself for DNS, netlogon starts before dns causing registration failures.


What's the default TTL for a SRV record, 30 days?

 

[mpapier]

I see my SRV records. Where can I find their TTL?

 

[mpapier]

Looking at the SOA tab, the Minimum (Default) TTL is 1 hour. Is that the value you were looking for? Or should I look elsewhere?

Anyone else have some thoughts on this? And suggestions are greatly appreciated.
Thank you
