Not able to telnet to server

Out of the blue for some odd reason I am no longer able to telnet to one of my SCO Unix servers. I can ping, ftp and do a traceroute to it, just cant telnet. When I attempt to telnet to it, I just get this

Trying ##.##.##.##....
telnet: Unable to connect to remote host: Connection timed out

What I don't understand is that other host within this office are able to telnet to this SCO server. Anything outside the subnet or remote sites are NOT able to telnet to this SCO machine. Could this be something internally with this server itself or could this have to do with some router settings being changed? Anyone have any suggestions??

Thanks

Problem solved! Turns out network provider made changes on their end. They disabled "telnet". Damm them!!

NAME
cports - expand host names into <host, server, port> triples SYNOPSIS
$CLUSTER_HOME/bin/cports hostname [hostname...] DESCRIPTION
The cports utility expands the hostname arguments into a list of <host, server, port> triples. The returned information is used to access the serial port consoles of the named hosts by way of the terminal server returned in the triples. If an entry for serialports has been made in the /etc/nisswitch.conf file, then the order of lookups is controlled by that entry. If there is no such file or no such entry, then the nameservice look up order is implicitly nis files. EXAMPLES
Example 1 Using the cports Command If the /etc/serialports file contains the entry: pepsi soda-tc 5002 the following command: % cports pepsi prints the following string: pepsi soda-tc 5002 This information can be used by the telnet(1) command to remotely access pepsi's console: % telnet soda-tc 5002 ATTRIBUTES
