Vpn stopped working
Site to Site VPN to my parent company's exchange server has been working for months then I get a call saying that no one can connect to the exchange server tonight.
I log into my Cisco 5505 and start the log and see errors when the tunnel tries to connect.
1) 3 Feb 11 2009 21:39:10 713048 IP = 142.176.xxx.xxx, Error processing payload: Payload ID: 1
2) 3 Feb 11 2009 21:39:10 713902 IP = 142.176.xxx.xxx, Removing peer from peer table failed, no match!
and
3) 4 Feb 11 2009 21:39:10 713903 IP = 142.176.87.114, Error: Unable to remove PeerTblEntry
I have no idea whats going on and I cant get in touch with the admin of the exchange server to see if he knows anything as to why
Attached is my running config. anyone see anything wrong?

try tearing down the tunnel and re-establishing it..
clear crypto ipsec sa
then send a ping over the network

no the IP is correct, just checked at another site, using a watchguard FW, and they are up. It seems to be only this one site affected.
Looked through the ADSM at the "top 10 access rules" and when i click on the exchange and say "show rule" I get Internal Error: Unable to find Access Rule
WTH??

keep in mind I'm semi new to the cisco
pretty weird,
if tunnel should either be both up or down at both sides.
try clear ipsec at both ends:
clear crypto ipsec sa peer x.x.x.x (internet address), This way, it will not break any other site 2 site tunnels.

yes, this is what i recommended in my previous post...
i was assuming he would be running the command from the site thats down.

Also are you sure nothing changed?
Do you have a backup to compare to?
If you are sure nothing has changed, (and have already tried the clear cryto stuff form above) try
wr me
to recompile the ACL's.

I tried the
clear crypto ipsec sa
that theoaks sugeested. no go
Currently looking for a backup. found one for my 1841 router but no luck yet on the 5505.
Will try the wr me shortly.
I was at home when the vpn went down, watching Duke v UNC, so I'm fairly certain nothing has changed

had no effect

Try to reload it. if it still does not work, upgrade to ver 8.0(4). There is a well know bug on ASA about VPN tunnel. I have couples customers having same issue.

Sorry I dont see ver 8.0(4) anywhere

the tunnel just broke for some reason.
If none of the config has change, i would suspect there has been a change on the internet address (142.176.87.114)
double check the internet address at both sides if it's still valid.
