Listers, I know you're not supposed to put Exchange on a DC, complicates backup and restore procedures in the event of disaster recovery. However I am sure that there are other reasons. Can anyone recommend where I can find a list of what these problems are. Yes - I have someone who is running it on a PDC and I need to tell them why not to.

Gents, I have a problem with our Exchange Server sp 5.5 on NT4.0 srv sp6a. The microsoft exchange internet mail service won't run. The error message in the event log is... The registry checkpoint for cluster resource Microsoft Exchange Internet Mail Service could not be restored to registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIMC. The resource may not function correctly. Make sure that no other processes have open handles to registry keys in this registry subtree. event id 1024. I also get another error message appear onscreen when i try and bring the internet mail service online, its Store.exe error The instruction at "0x70247270" referenced memory at "0x000000014". The memory could not be "read". This error message also appeared a few times when i tried to login to hotmail on internet explorer on the server. When i clicked on ok it closed the browser. This might suggest that the problem is with the server and not just with the exchange services. I've checked the disk space, tried stopping and restarting all the different services, rebooted the server, checked for any signs of viruses on the servers (eg code red variations as our servers do not have antivirus software on them - no sign of any viruses). I've already looked around on technet for hours and cannot find much on this error at all. Any assistance on this one would be greatly appreciated. thanks, James Johnston _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
