You've oversnipped, so I can't tell whom you're addressing this to. However, I must say that everyone who has posted "There /is/ no M: drive" knows exactly what the M: drive is, what it's there for, and why and under what circumstances you'd use it. The mantra "There is no M: drive" is for people who want to go in and use file-level backup and antivirus utilities on it, muck about with permissions, etc. without having any idea what the EXIFS is and subsequently wonder why they've brought their enterprise messaging solution to its knees. It's a short way of saying, "If you have to ask, don't touch it without asking your employer to demote you to intern and hire someone qualified to do your job."

Subject: RE: Drive m:???? pardon me for sounding so partonizing, but the M drive is the installable file system that ships with exchange. As you know all internet protocols (http, smtp, nntp, pop, imap) are now server by the same engine that does IIS. IIS consults the Exhcange store and a file handle to the item you are looking for in the Exchange store is returned. This is a true NTFS file handle and is provided by the EPoxy or EXIPC mechanism which masquarades exchange items as NTFS file handles using an asynchornous work queue which is extremely fast and provides little context switching. Think of it as another file system driver just the same as FAT, NTFS, CDFS, HPFS. The reason some of you do and some of you don't see an M drive is because IIS launches (specifically the W3svc service) before your exchange store service completes it start up process. Hence no M drive. All you do is bounce your w3svc service and you will have an M Drive. I chose to change HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC and make DependOnService have the value of MSExchangeIS. You can change the drive letter by editing the following registry key. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EXIFS\Parameters On the Edit menu, click Add Value, and then add the following registry value: Value Name: DriveLetter Data Type: REG_SZ Value: P NOTE: If the DriveLetter value already exists, double-click the value, and then change the drive to n: or another letter. One more point about the EXIFS (Exchange Installable File System) - there are three methods of application deployment - xcopy from the file system, ftp, or email or sending data to an exchange public folder. NT admins like xcopy, web admins like ftp or webdave, exchange admins like to deploy to public folders. EXIFS provides a mechisim to keep everyone happy. --Felicity _________________________________________________________________ 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]
