Sbs 2003 DHCP keeps stopping

I have SBS 2003 on VMware ESX 3i on a proliant ML350 G3 routing through a Linksys wireless router with the DHCP turned off on the router.

For some reason the SBS DHCP server keeps randomly stopping. Even when its on it gives the wrong configuration to clients. i have to manually put in the settings to be in my domain.

I have the scope set up how i want it. Router, wins server, gateway, etc. all set to SBS server except the gateway. Forwarder is set to ISP

TCP/IP config is set on the server to the loopback.

I've looked all over the internet trying to figure this out but to no avail. First post, i've read this place a long time, you guys always give correct answers.

gotta run the CIECW wizard.... that does all the configuration including scope, range for DHCP. Also many use the 1 NIC configuration but SBS really works better with the 2 NIC configuration.

Example:
This might work.

Do you have a router or anything that could be acting as a DHCP server anywhere on your network (including the ISP's router)? If so, that's the cause of your problem. Assuming you have a fixed IP on your Internet NIC,
you could try unbinding DHCP from that NIC, which should fix it if it's the ISP's router.

turns out i found that i have a dns hijacker. it started on one machine and is now on my laptop. any ideas?

by Former member

This DNS hijack seems to be fairly new and thus I recommend to all that you check your settings. My Spybot S&D did not catch this issue, nor any of my anti-browser hijack programs.

Download HijackThis and run it and then go to the site below to analyze it to find out what you are infected with. It may give us a clue.

HijackThis log file analysis

Hijack This opens you a possibility to find and fix nasty entries on your computer easier. Therefore it will scan special parts in the registry and on your harddisk and compare them with the default settings. If there is some abnormality detected on your computer HijackThis will save them into a logfile. In order to find out what entries are nasty and what are installed by the user, you need some background information.

A logfile is not so easy to analyze. Even for an advanced computer user. With the help of this automatic analyzer you are able to get some additional support. Just paste your complete logfile into the textbox at the bottom of this page. Due to a few misunderstandings, I just want to make it clear that this site provides only an online analysis, and not HijackThis the program.

You can also try this.
Download Malwarebytes Anti-Malware, install it and update it and scan the PC's.

hey thanks for that. malwarebytes was the only program to successfully remove it. much appreciate it. Hijack this wasn't able to which is odd cuz it usually removes everything
