Hi All I have Windows 2008 R2 as Domain Controller. I am installing Exchange 2003 server on Windows 2003 Server. But during the install it fails with error: "Setup failed while installing sub-component Exchnage System Management Snap-ins with error code 0x0C103798A (Please consult the installation logs for a detailed description). You may cancel the installation ot try the failed step again." Netdiag, DC diag - has no errors or failures Ran ForestPrep and DomainPrep - no errors during install Did research and found MS KB 887723 but that sounds irrelevant as the setup failes during the install and in this artcle seems the changes are recommended in Exchange Interface. Any help on this will be highly appreciated. Thanks Bhasker P

Hi, Can you post the log file called "Exchange Server Setup Progress.log" that is in the root of the system drive? http://technet.microsoft.com/en-us/library/bb124620(EXCHG.65).aspx -- Mike Burr

Thanks Mike. Where can I upload the file. I dont see any option to upload the file and the log file size is 4MB. Bhasker

Below is in the log when the error generates: [01:29:36] Interpreting line <CreateProcess:C:\Program Files\Exchsrvr\bin;regsvr32.exe -s pop3adm.dll;180000> -- ID:31259 -- [01:29:36] Process created ... waiting (180000) [01:29:36] Process has exited with 00000000 [01:29:36] Interpreting line <CreateProcess:C:\Program Files\Exchsrvr\bin;regsvr32.exe -s cdoexm.dll;180000> -- ID:31259 -- [01:29:36] Process created ... waiting (180000) [01:29:36] Process has exited with 0x000003 [01:29:36] The command regsvr32.exe -s cdoexm.dll failed, returning error code 3 (The system cannot find the path specified.). -- ID:31136 -- ScCreateProcess (f:\titanium\admin\src\libs\exsetup\hiddenw1.cxx:1821) Error code 0XC103798A (31114): An internal component has failed.

That's sort of large for a forum post. Near the bottom when you installed the Exchange component, are there any sections that seem to show the error that occurred and can you post 20-40 lines above and below that in a forum reply? -- Mike Burr

Hi, As this issue is related to Exchange Server, I suggest discussing it in our Exchange Server forum. They are the best resource to troubleshoot this issue. http://social.technet.microsoft.com/Forums/en/category/exchangeserver/ Tim Quan
