I am running exchange server 2007 64-bit on a windows 2008 server, everytime i try togo to the OWA page it loads about:blank in both frames. Any suggestions?

Early bird suggestion Install SP1 Update Rollups 3 and check if it is not installed.

Hi, Whether logon.aspx has been customized? Please confirm whether this issue would occur when you access OWA internally. Whether it has been published by ISA to internet. If the issue occur when you access OWA internal, then please follow kb 941201 to delete and re-create Outlook Web Access-related virtual directories Reset OWA related Virtual Directory http://support.microsoft.com/kb/941201/en-us How to create and manage configuration backups in Internet Information Services 7.0 http://support.microsoft.com/kb/954872 BTW, please try to check application log to see whether any related event has been logged there Note: Run eventvwr to open event viewer. Hope it helps. Xiu
