You get reports that Windows users cannot log in anymore when the main MPLS link is down. The
message that users receive is, “There are currently no login servers available to service the login
request.” However, if you modify the MTU of the client machine to 1294, the user can log in. What
would be a reliable fix for this issue?
A.
add “ip tcp mss-adjust 1254” to se1/0/0
B.
add “ip tcp mss-adjust 1254” to se1/0/0 and fa1/0
C.
force Windows to use TCP for Kerberos
D.
add “ip icmp error-send” to se1/0/0
Explanation:
You can force windows to use TCP for Kerberos so that even if you modify MTU of the client
machine to 1294, use cannot log in.
