We have a set of users who access some of our web applications through WebVPN, however where an application uses resources on a CDN e.g. CSS/JS, the url for the resources is being rewritten by WebVPN and then the application fails because it's trying to load files from urls that don't exist.
What changes do we need to make to the WebVPN configuration to make our applications work correctly?
We're building a new set of web servers to be located in a DMZ, but we want them to be able to use our internal mail server. The mail server has a CNAME of smtp.uk.ourdomain.com - our existing servers have an entry for this in their hosts file. However the actual mail server behind the smtp... CNAME may change periodically for maintenance, patching etc and currently if we want the web servers to keep up with this we have manually update the hosts file on each server.
Instead of a hosts file entry we want our new servers to be able to use DNS so they only ever send traffic to the smtp CNAME and let DNS do the name resolution, however we think there's a risk that if our web server gets pwned we're then exposing our internal network. What's the best way to set these servers up so they're secure but can resolve the names of the services we need from the internal network?
Is there a way to query our internal DNS entries to discover all the CNAME entries that point to a particular server?
Edit: We're a Windows environment, Server 2003.
I'm struggling to understand how to do differencing disks in VirtualBox v3.1.0. I've created a Windows 2008 Server, but now I want to use that as a base image for a number of other servers. The help file has a description of what differencing disks are, but I can't find where it actually tells you how to do it. In the Storage dialog for a server I found the Differencing Disks checkbox: alt text http://www.philippursglove.com/stackoverflow/virtualbox%20differencing%20disks.png but when I check it, I'd expect it to then ask which image should be the parent so I could select my base image.
Any pointers you can offer would be greatly appreciated!
I'm trying to set up a pair of virtual (Win 2008 Server) servers on my laptop for demo'ing Velocity. I've got my first server setup with VirtualBox, but I'm slightly clueless about how to set up the networking so that host and guest can talk to each other. Both guests will also need to be able to talk to each other. The guests don't need to be able to talk to the outside Internet though it may be nice to have.
Do I need a virtual network? How do I set it up?
I often have to remote onto live servers. When I'm done, I go to the Start menu to log off, but the Shut Down button is always lying in wait for me and trying to get me to shut down a live server. Is there any way that it can be removed from my Start menu e.g. registry switch? If it could be removed on a per-user basis, that would be even better.
We've started to see instances on our Intranet server where for any page the server just responds with the error page 'HTTP/1.1 New Session Failed'. It seems we can fix it by running IISRESET but this feels like we're only treating the symptom.
The server is a virtualised server running IIS6 on Windows Server 2003 with 0.5Gb of RAM. Our Intranet is written in ASP, but we also have ASP.NET 2.0 applications running on the web site. The site is set up for Anonymous and Integrated Authentication.
What causes IIS to get into this error state? Could the server be saturated with requests i.e. we need to scale out and move some applications onto another server?
I've seen KB210842 but I'm not sure it applies as that is applicable to IIS 4
