10060 Timeout #2 - 16.Aug.2007 10:57:30 AM

Hi there,

We have a problem with our web connection, this is kind of similar to some of the other 10060 errors posted in this forum but not the same.

Every so often, for about 10 minutes, anyone that tries to access a web page will receive the 10060 timeout message. Sometimes it will be able to get to one of the frames but the rest of the page times out, others it will timeout completly.

This happened yesterday and lasted about 15 minutes (it has happened several times before). I was able to go out through a different route, bypassing the ISA server. Whilst going out through this connection I used our own DNS server and two of our ISP's DNS servers. These tests worked fine.

Whilst I was doing these tests there was another user trying to access the pages going through the ISA server and they were continually having problems.

This has effectively ruled out our ISP's DNS servers, our own DNS servers and, as it was several differnet pages that we were testing, it just leads me to beleive that the problem lies in the ISA server somewhere.

I am no ISA expert and have been unable to find the route cause of this problem. I am going to run the Microsoft Best Practice Analyser on the ISA server at the weekend to see if it throws up anything obvious but I thought that I would ask here as I would guess that if anyone would know it would be you guys.

Any help would be highly appreciated.

If you need any more info then just ask.

Afternoon,

There have been alot of views to this thead but no responses, either means that nobody knows or that nobody likes me :(

I have an update to this issue.

At the time of posting this message we had three DNS servers, however only one was acting as a DNS forwarder.

I have amended this so that all three servers can act as DNS forwarders and amended our DHCP settings so that roughly half are pointing to server 1 as there first DNS servers and half are pointing to server 3 as there DNS servers.

After I made this change everything started running very smoothly however recently the problem has started occuring again.

It is not as prominent as it was previously, lasting perhaps 2 mins and only occuring sporadically rather than every day.

I have looked through the event logs for all our DNS servers and our ISA server and there doesnt seem to be anything of note in there. I also have performance monitors running on all the servers and again, there doesnt seem to be anything of note.

Any help\advice would be highly appreciated.

Is this occurring for several sites or just one site. If the former does it re-occur for the same sites?

Have you considered setting up an HTTP connectivity verifier in ISA, for the site(s) in question?

Which Service pack you have loaded on your ISA server ??
