Exchange 2003 connection problem (IMAP)

Find a solution for IMAP connection problems on a Windows Small Business Server 2003. Using Microsoft Remote Connection Analyzer, the following test results are shown below. I suggest we are using a remote desktop application to work on the problem (directly on the server): [login to view URL]: Unable to read data from the transport connection: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ---> [login to view URL]: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond at [login to view URL](Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at [login to view URL](Byte[] buffer, Int32 offset, Int32 size) at [login to view URL](Byte[] buffer, Int32 offset, Int32 count) at [login to view URL](Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at [login to view URL](Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at [login to view URL](Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at [login to view URL](Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at [login to view URL](Byte[] buffer, Int32 offset, Int32 count) at [login to view URL]() at [login to view URL](String command, String logString) at [login to view URL]() Elapsed Time: 61261 ms.
