Re: strange problems
Does the DC that goes down also a Global? From: Fyodorov, Andrey [EMAIL PROTECTED] Reply-To: Exchange Discussions [EMAIL PROTECTED] To: Exchange Discussions [EMAIL PROTECTED] Subject: strange problems Date: Tue, 30 Sep 2003 15:37:53 -0400 Hi all. We are having some interesting problems with one of our Exchange 2000 SP3 cluster. I wonder is anyone here has seen something like this. It seems that whenever a DC *in another AD site* goes offline, this particular Exchange server starts acting up: users can't connect to the server with Outlook, ESM reports that the stores are dismounted, refreshing the storage group view produces an error that Information Store service may not be running, intermittently the stores seem to mount again, then again appear dismounted. Why would Exchange start acting up like this if one of many DCs goes offline, especially if this DC is in another AD site? We end up failing over the cluster to another node and the server is happy again, until next time. Also another (but I believe related) issue - today a DC in the same AD site went offline and caused all users whose mailboxes are homed on this cluster to receive Error 500 Internal Server Error in OWA. We had to change the server properties under the DS Access tab to manually list good DCs instead of letting Exchange discover DCs automatically, then failed over the cluster - OWA started working fine again. The other two Exchange 2000 SP3 clusters did not get affected by this at all. To the best of my knowledge all these clusters are built the same. They sit in the same rack. They are on the same VLAN. They use the same hardware. They are up to the same SP and patch levels. Any ideas?

RE: strange problems
Not sure about the DC in the other site. It is currently down, can't get to it to check. The DC in the same site that went down today was not a GC, however it had been autodiscovered by Exchange as a Configuration DC. Also I just straightened out another issue - this server has multiple NICs and all of them had NetBIOS bindings (MS Client and File and Print). I removed NetBIOS bindings from the NICs that don't need it (cluster heartbeat NICs) as it was causing Browser to get disoriented.

RE: strange problems
I had better luck in NT4 and multihomed NIC's than in Win2K. I have the unfortunate need to make my Exchange box a DC which is also multihiomed (The the main DC but still). The hoops you need to go through in Win2K is pretty serious. A lot of 'Q' articles on multihoming DC's (with DNS) and NetBIOS etc... -Original Message- From: Fyodorov, Andrey [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 30, 2003 14:28 To: Exchange Discussions Subject: RE: strange problems Not sure about the DC in the other site.

RE: strange problems
Nothing unusual. Until today, it was set up to automatically discover DCs and the DCs from local site were listed as discovered. After today's OWA problem (caused by a DC in the local site going down) we manually listed the DCs that are still up.
