All of a web page doesn't come up

[NetworkDOC]

This is a puzzling issue.

Users are behind a 2600 rtr with the firewall feature set. All seemed to be working fine until recently. When any user or server goes to the Internet, (yahoo.com for example) the pages come back incomplete. No errors on the page just not filled in. Take one of those same laptops and take it home and it works flawlessly.

I ran continous pings from that laptop to the internet and get no time outs or bad response times (all were around 60-70 ms. Ran for several minutes. Tried bringing up the web page to yahoo as I was pinging it. Still the same results and no time outs.

I can't put my finger on what the problem is. Any ideas?

Have you upgraded the IOS (and feature set?)
With the PIX os the http insepction allows you to turn off certain data in web traffic (activex, java, etc.)

Set your syslog to debug and see what shows in the log.

Well... Here is what I think was the answer. The mail server caught a virus. This was consuming all the bandwidth (the verdict is still out on that). I am not sure why this wasn't detectable when I ran continous pings. It seems fine for now.

Awful strange though....

Thanks Ya'll

...yea that is odd...
...how did you detect the virus?
...did you notice the bandwidth issue 1st...or did you notice the virus first from software..

Actually we noticed that the queue was filling up within seconds on the mail server. Then it would saturate the t1. This was repeating quite regularly.

...wow..
..so because of the virus was it the mail server or clients of the mail server that where creating mails..sorry for dumb question..just trying to learn..
..also do you know what virus? and how did you kill the virus?
..thanx for any info...

The virus was one that generated tremendous emails. I will have to look for the name of it. Downloaded the .dat file and was able to clear it out that way.

BTW. Is that Ral NC?

 

[DanInRaleigh]
