Exchange 5.5 connector Error

• I have loaded a exchange conntector from a third party application on my Exhange 5.5 box. (SP4) The server is NT4 SP6A. The connector published successfully to exchange but I hve a small glitch when I go to click on it. Have a look at the error below. http://www.sprint.net.au/~fabiand/images/error.bmp I have the exchange setup correctly eg all this work work done with the same domain admin account. All parts of the exchange tree have full service access with this account. If I click ignore on the image the connector still loads ok. So I am little confused on whether it is working or not? What I did for a test is install the exchange administrator (with SP4) on a W2K server and connected it to the NT4 server. When I click on the connector in W2K I do not get this error. So I assuming that it is a NT error somewhere? I have not re applied any service packs yet. Any ideas?

  Howdy fabios_ss! Microsoft Knowledge Base Article - 183414 describes your problem pretty much spot on, but under somewhat different circumstances. Regardless, all of the articles point to a missing/damaged/corrupt Mfc42.dll file being on your NT box. http://support.microsoft.com/default.aspx?scid=kb;en-us;183414 "The information in this article applies to: Microsoft Exchange Server 5.5 ... SYMPTOMS ... the following error message may be displayed: The extension [smtp] could not be loaded. The error 87 occurred while formatting Windows NT error 182. Microsoft Windows NT ID No 0xc00200b6. CAUSE This problem can occur when the Mfc42.dll file in the Winnt\System32 folder is missing or damaged. WORKAROUND To work around this problem, follow these steps: Rename the Mfc42.dll file in the Winnt\System32 folder, if it exists. [ You might want to rename it to something such as Mfc42.dll.old ] Copy the Mfc42.dll file from the Server\Setup\I386 or Server\Setup\Alpha folder on the Exchange Server 5.5 CD-ROM to the Winnt\System32 folder on your hard disk. To do so, type the following command at a command prompt, and then press ENTER: copy <drive>:\server\setup\<platform>\mfc42.dll c:\winnt\system32 where <drive> is letter of your CD-ROM drive and <platform> is the appropriate folder on the CD-ROM (I386 or Alpha). Quit and restart the ... program. If this does not resolve the problem, another successful workaround has been to remove and reinstall the Exchange Administrator using the Exchange Setup program." There are additional things to check and additional workarounds at the Microsoft Knowledge Base Article - 186787 http://support.microsoft.com/default.aspx?scid=kb;en-us;186787 You might also check the third party application directory, etc. for an updated version of the Mfc42.dll file if none of the above work.
