My projects were working on PWS, and now I switched to IIS on Windows 2000 Pro. After I installed IIS and run my project, I received the following error for database connection. <BR><BR>Error Type:<BR>Server object, ASP 0177 (0x8007007E)<BR>8007007e<BR>/myatt1/onl_commu/msgboard.asp, line 32<BR> <BR>My code to open database is:<BR> <BR>Set objConn = Server.CreateObject ("ADODB.Connection")<BR> <BR>I searched the problem in and found that I need to install a dll file, but I don&#039;t know which one. Can anyone help me? <BR><BR>Thanks in advance.<BR>
