I keep getting bounced around...exchange forum sent me to the iis forum and the iis forum has sent me back to the exchange forum. Can anybody help?? Why does the www service on my new exchange server keep disabling itself? Our original server is an Exchange 2000 and it runs fine. We have added an Exchange 2003 server to the network and it runs fine, except that the www service keeps disabling itself. I have to enable and start it a couple times a day or more. What could cause this? Original Server Specs: Windows 2000 SP4 Exchange 2000 Enterprise - Version 6.0 (Build6249.4: Service Pack 3) New server Specs: Windows 2003 Enterprise SP2 Exchange 2003 Enterprise - Version 6.5 (Build 7638.2: Service Pack 2)

Is there any error event in the application log on the exchange 2003 server after reproduced the issue? Please run ExBPA against the exchange 2003 server for health check

Here the two errors in the application log:OALGen could not find the address list with the Active Directory object GUID of '/guid=B1D748F52D310E41AF34D3F1228C0883' in the list of available address lists. Please check the offline address list configuration object. OALGen encountered error 8004010f while initializing the offline address list generation process. No offline address lists have been generated. Please check the event log for more information. Here is the results of the ExBPA: Exchange mailbox server email.domain.com has 1 GB or more of memory, accommodates 20 mailboxes, and does not have /3GB set in the Boot.ini file. Greater scalability would be achieved if this were set. Memory detected: 3927 MB.Server email.domain.com has 1 GB or more of memory, accommodates 20 mailboxes, and the 'HeapDeCommitFreeBlockThreshold' parameter has not been set to 262144. Virtual memory may become quickly fragmented and system instability may occur.

Nothing in the event logs? What other 3rd party software is installed on the Exch server? (A/V, anti-spam, etc..)

Well, the error events (9334, 9344) seem related to OAB generation rather than WWW service. Do you encounter related issue about OAB? Can the OAB be downloaded successfully? Please enable the diagnostic logging: Server->Properties->Diagnostic logging ->MsExchangeSA ->OAL Generator Please check at the “Properties” of mailbox store and verify if it was pointing to right OAB: Mailbox store ->Properties->General Please check the “Properties” of Default Offline Address List, and delete those entries from there except the Default Global Address List. Then rebuild the Default Offline Address List. After that, set the “Maintenance Interval” to “Run Now” at the “Properties” of public store

Are you running any kind of websites? on this server? may be some av is creating a website which might be causing the issue? check for port used by websitesVinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Following your instructions I have gotten the OAB working properly. I'll find out tonight if the www service is still a problem. Thanks!!

Does the issue being solved?

No, the www service still disables itself. :-(

Please refer KB 320202 to reinstall IIS on the exchange server

Just finished reinstalling IIS. I followed all instructions. After the reinstall it took about an hour before the www service disabled itself again. :-(

If there's any futher related error info, please post at here for analysing

No luck here. I am just going to reformat and start over. Argh...

Hi All,It seems that this problem is occur due to windows update. I think u have uninstall the updates from server and then check IIS and install back the updates one by one and check that which update is stoping iis. If you will reformate the system this problem my occur again.
