Companyweb error messages

The issue seems to have started after doing a clean install when a setup error message read Sharepoint Services did not install properly. We then proceeded by running this part again as requested. Then we carried on with the installation including the Windows SBS 2003 Premium Edition SErvice pack 1 through to 3, from this disk set ISA 2004 disk would not install.

The problem that you are getting could be caused by an error in the way that certain dynamic-link libraries (DLLs) are validated. The installation process incorrectly interprets some DLLs as not valid when, in fact, they are valid. To resolve this issue, first download and install software update 909544 by going to this link - http://support.microsoft.com/?id=832880
