Exchange2010 OWA issue
There are 2 exchange 2010 servers with NLB load balance, 2 CAS/HUB roles on each server. The NLB is working on multicast mode. When I connected OWA with NLB virtual IP and refresh web page, OWA will turn back to the logon screen at once. sometimes " clientstrings.aspx syntax error" occur. But if I use one of CAS host IPs(non-NLB IP) to log on to OWA, OWA is working normally. RSS is disabled. Don't find related errors on logs and events. Appreciated for your help.
