I installed php4 on windows 2000 advanced server and it works fine. I placed the php4_mssql.dll file in C:\php\ and in the extensions I uncommented the line to load the dll. When I run a php script I get this error "Unable to load dynamic link library './php_mssql.dll' - Access is denied."
I have sql server 2000 installed with the client tools. According to php.net this all should work. If anyone knows about this error and any help in general would be great.
