i have two problems :
1. i configured ip on a win XP m/c that had two LAN cards , one for internal LAN and another for external.the problem is that when i ping the system with its hostname or local host ip "127.0.0.1" it pings but when i ping using either of the ips i configured on cards it gives "ttl expired in transit".also after configuring the ips the m/c sometimes asks for restart sometimes not.what is the reason?is it any virus?Also could u please tell me what is the difference between the two icmp errors "request timedout" and "ttl expired in transit".
2. i connected cisco 1721 router with consol port.when i tried to access using hyperterminal it gives a blank cursor not the "router>" prompt which it should.what may be the problem?
thankns for help...
