Hello, I am very new to forums as well as working with servers so please bear with me if I have done this wrong. I recently started managing a new server with SBS 2008 installed. All seems to be working fine with the exception of OWA. Clients (within the network and without) can all access the remote splash page but when they try to check their email via the icon for OWA it seems to hang, then an error shows up: Outlook Web Access did not initialize. An event has been logged so that the system administrator can resolve the issue. No more threads can be created in the system. (Exception from HRESULT: 0x800700A4) Request Url: https://remote.mycompanyname.com:443/owa/auth/error.aspx?aspxerrorpath=/owa/default.aspx User host address: 192.168.11.160 Exception Exception type: System.Runtime.InteropServices.COMException Exception message: No more threads can be created in the system. (Exception from HRESULT: 0x800700A4) Call stack System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) System.Management.ManagementEventWatcher.Start() Microsoft.Exchange.Clients.Owa.Core.OwaRegistryKeys.RegisterSMIMERegistryChangeEvent() Microsoft.Exchange.Clients.Owa.Core.OwaRegistryKeys.Initialize() Microsoft.Exchange.Clients.Owa.Core.Globals.InitializeApplication() Microsoft.Exchange.Clients.Owa.Core.Global.ExecuteApplicationStart(Object sender, EventArgs e) I have searched many forums for this exception and can't seem to find any answers. There seem to be 2 immediate event logs: 1. (warning): ASP.NET 2.0.50727.0 EventID 1309 Exception information: Exception type: COMException Exception message: No more threads can be created in the system. (Exception from HRESULT: 0x800700A4) 2. (error): Windows SharePoint Services 3 Search EventID 2424 The update cannot be started because the content sources cannot be accessed. Fix the errors and try the update again. Context: Application 'Search', Catalog 'index file on the search server Search' One thing to note: no matter what a client does to accept/install the certificate when logging in from home it is never trusted. Any help on this would be greatly appreciated, if I have posted in the wrong place my apologies. Regards

Hi, First please ensure that you have the latest (Rollup 7) update for Exchange Server has been applied. Then lets try to follow the steps below to narrow down the cause of the issue. 1. Please try to access OWA with https://serverip/owa and then test the issue. 2. Please try to access OWA with https://servername/owa and then test the issue. 3. Please try to access OWA with https://domainname/owa inside the network and outside the network to test the issue. 4. Please try to access OWA and then click other folders to see if any error would occur. 5. Please try to run ExBPA to have a health scan and then post the error report here. 6. Please try to check event log and then post the error event here with detail error information and event ID. Besides, base on my research, this issue may occur when WMI corrupts, so we may try to re-register the WMI files and recompile the MOF files. 1. Please disable and stop the WMI service.(We can run services.msc from a command prompt to open services manager.) 2. Please run the command below to re-register the WMI files: cd /d %windir%\system32\wbem for /f %s in ('dir /b *.dll') do regsvr32 /s %sregsvr32 %windir%\system32\tscfgwmi.dllwmiprvse /regserverwinmgmt /regserver 3. Please run the command below to Recompile mof and mfl files and then reboot the server. for /f %s in ('dir /b *.mof *.mfl') do mofcomp %s net start winmgmt More information to share with you: WMI Troubleshooting: The Repository on Vista / Server 2008 http://blogs.technet.com/askperf/archive/2008/07/11/wmi-troubleshooting-the-repository-on-vista-server-2008.aspx Regards,Xiu

Thank you very much, I will start right away beginning with Rollup 7. It may take me a while but I will post the results as soon as I get them as I am on a business trip next week. Regards,
