Hello, I don’t know if its the right place for my question but I will try. In my organization we have 2 Exchange 2007 Standard SP 2 servers , one of them is responsible to generate the OAB (Offline address book) for some time on this server are coming two errors all the time in 15 minutes intervals: Log Name: Application Source: MSExchangeFDS Date: 4/21/2010 2:20:28 PM Event ID: 1018 Task Category: General Level: Warning Keywords: Classic User: N/A Computer: SERVER1.domain.pl Description: Process MSExchangeFDS.exe (PID=3596). Failed to connect to remote server SERVER1. The remote server may be down, or its Server service may not be running. Log Name: Application Source: MSExchangeFDS Date: 4/21/2010 2:20:28 PM Event ID: 1028 Task Category: General Level: Error Keywords: Classic User: N/A Computer: SERVER1.domain.pl Description: Process MSExchangeFDS.exe (PID=3596). Errors occurred while content was being synchronized from Unified Messaging server "SERVER1" for object "Default OAB". The remote server is unavailable. The local server stopped trying to synchronize after 5 retries. Check the previous error events that were logged by Microsoft Exchange File Distribution Service for more information. The funniest thing is that in the log is written that the server SERVER1 “Failed to connect to remote server SERVER1” SERVER1 is its own name. I have tried many different things but without result.I have found this problem on technet but the solution written there doesn’t help. Both Servers are fully update. I’m almost certain that those errors are causing a another problem in my organization. People are having problems when new people are hired and the get an exchange mailbox that they cannot find the new people contacts in the Outlooks Global Address List. Can someone help me with this? Regardsgomeziak

Can you map a drive to \\server1\ipc$?Active Directory, 4th Edition - www.briandesmond.com/ad4/

Hello, you are right I cannot map a drive to \\server1\ipc$

http://strony.aster.pl/gomez99/exch1.JPG The first screen shows that the OAB is shared but on the share permissions is writen "not shared". I can access the OAB share from my PC. http://strony.aster.pl/gomez99/exch2.JPG The second one shows the folder perms. Is there something maybe missing?

I can access the OAB share from my PC. You need to fix that file sharing problem. Is file sharing enabled on your server? The other place you want to look is the ...\ClientAccess\OAB directory. It shouldn't be shared and the directory permissions should give the Administrators and Local System "Full Control". --- Rich Matheisen MCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

It seems that there is an another problem causing this. When I’m logged on this server it’s impossible to open a network share from a another server/computer on the network error “0x80070035 The network path was not found” this same error appears when I try to open the shared folders \\SERVER1\ from its own. When I’m on my desktop and trying to open \\SERVER1\ everything works and I have access to the exchange servers files. Ping is working to every server/PC, name resolution works also fine. What can it be, or how diagnose this problem because nothing else is in logs?

When you're logged on to the server nobody else on the network can browse the shares on it? If they run "net view \\<servername>" they get the error "53" that says the network path is not found? If you log off the server and they run "net view \\<servername>" they can enumerate the server's shares? While you're logged on to the server, is the "Computer Browser" service running? While you're logged on to the server, can you "telnet <servername> 445"? You should get a blank screen but you shouldn't get a connection failed error. Can others do this from their workstations? If you get different results when you're not logged on that would be very strange. It's certainly not an Exchange problem, though. You'd get better help in the appropriate Windows server forum. >When I?m on my desktop and trying to open \\SERVER1\ everything works and I have access to the exchange servers files. So if you never log on to the server the OAB stuff works correctly? --- Rich Matheisen MCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

Hello, Please check with the OAB Default Permissions on the share folder. http://blogs.msdn.com/dgoldman/archive/2007/02/01/exchange-2007-oab-generation-fails-with-errors-9348-and-9109.aspx http://technet.microsoft.com/en-us/library/bb310776(EXCHG.80).aspx Thanks MHussain

Hello, those things that you wrote are working so it can be a 2008 operating system related thing. Thanks for help I will try it on the system forum.

Hi, Please understand that the Microsoft Exchange File Distribution service attempts to contact the OAB generation server five times to access ExchangeOAB shared folder to copy the OAB files from Mailbox server to the CAS server. If the ExchangeOAB shared folder is not configured right, that will cause the error. Thanks Allen

Hello, I came out that an update was causing this problem, after uninstalling this security update everything is working fine. The update was: KB971657
