SYMPTOMS
When you attempt to connect to a Telnet server using the Windows NT version 3.5 Telnet client utility, the connection attempt times out.



CAUSE
A non-terminating acknowledgment (ACK) loop of Telnet IAC commands is initiated between the Windows NT computer and the Telnet server. This problem may be due to these reasons:


 * The Telnet server is sending an ACK when it receives a request to enter a mode that it is already in.
 * The Windows NT Telnet client utility is not keeping track of previous IAC command sequence(s).



WORKAROUND
Contact the manufacturer of the Telnet server for more information.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.5. This problem was corrected in Windows NT version 3.51.
