I have a back to back ISA server setup and I am setting up logging to a SQL Database. I have made 2 database 1 for each ISA Server. The inside firewall is able to log to the SQL database without any problems. I have published the SQL server to the outside firewall and Tested my DSN and the DSN passes. When I go to setup the logs to the SQL server I get the following in event viewer: The Microsoft ISA Server Control was unable to open ODBC Data Source sgiserver6, Table: PacketFilterLog, under User Name [isa1]. The ODBC Error description is: Overlapped I/O operation is in progress. . For more information about this event, see ISA Server Help. Any help is appreciated. Steve
