There are two servers, which are Windows NT with IIS 4.0 and Windows 2003 With IIS 6.0, served by CSS 11506 running WebNS 7.20.206. The load balacing mode configured at CSS is least connection and stickiness enabled as well as flow timeout multipler is 5400.
I experienced a problem that TCP connection counter for Windows 2003 Server (by usng "show rule ... service" command) is not cleared by CSS when the TCP session is closed. However, it seems normal at NT server side. As a result, all new client connection is forwarded into NT server because of least connection balance mechanism. Would anyone tell me how can fix the problem.
