Unable to reach one particular URL..Not what you think!!

[lastexile69]

Hi
We have encountered a weird problem here at my office - no pcs or macs anywhere in the building can connect to adobe.com or any other URL that has adobe.com in it.

However, when the adobe programs resident on various pcs and macs do their own search for automatic updates, they work!

I want to be able to donwload fresh drivers etc as they become available, or even just the free Adobe reader for example, but I can't make a connection to anything with adobe.com in the URL.

Is there a block somewhere on my Exchange server or at my ISP that I should be investigating?

Or something far simpler than that?

Any help really appreciated. Cheers.

I would suggest either something internal is blocking it or it is an IP address range conflict.

What is your internal address range would it be anything like this - 192.150.18.117 <- this is adobe.com

Check with whoever looks after your DNS server you are pointed to. Also check /windows/etc/drivers/hosts. file on PC's to see if there ate any entries there ( only entires should have a # at the start of each line)

also put http://192.150.18.117 into your browser and see what you get ( i get an adobe error page)

try tracert www.adobe.com . This will tell you 2 things.

1. If the DNS is working and setup then you should get an IP address for adobe, I get 192.150.18.200
2. Tracert will wander along the route to adobe, you should be able to work out where the problem lies by where it fails

FWIW it will probably be a range of IP addresses in 192.150.18.x ( i get .60 for adobe.com and .117 for www.adobe.com) they will use a round robin DNS or similar to share the load. Interestingly (or not..) .200 displayed adboe's site fine and .117 gave a 404 error

or use opendns

also, have you checked someone hasn't bodged the hosts file on the firewall ?

I hear wonky versions of photoshop add some adobe dns entries to the hosts file pointing at localhost.
