This is the blog of A.J.Anto. I work as a developer in DHCP in the Windows team. Everything here is "as is", my words only, not the official word of Microsoft, nothing here supported by PSS, etc and it comes with no warranties. Btw, If any body finds out an interesting peice of information (This can be anything from a documentation link to a sample code.) regarding DHCP technology especially with respect to Microsoft's implementation of it and want to contribute to this blog, please contact me using the alisa anto_rocks@yahoo.co.in . I will put it on my blog so that it is available for wider audience.

All about DHCP vendor classes and user classes.

How do you find out the instantaneous load of the DHCP server?

Many network administrators would like to know the instantaneous load on their DHCP servers. This is possible on Windows Server 2003. The downside is that this cannot be done directly via the GUI or the net shell commands. You can go to the perfmon by
