Hi

I need a NT hosting for hosting six domain names.

The configurations must be:
Windows NT Server with IIS 4 .
2 domain must have unlimited POP3.
Unlimited Data Transfer
All domains need 20-50mb webspace.
All domains need 1 -3 DSNs.
PHP3
Cold Fusion

I also need installing PC anywhere for remote access.

Sounds like you need a dedicated server. I use 2CoolWeb. The service is the best I've ever had and I would suggest emailing them for a quote.
Check out the reseller program. http://www.2coolweb.com/

Try Host Experts.net at http://www.hostexperts.net

For remote access via PcAnywhere you will need exclusive access to the machine, hence a dedicated server. For NT dedicated servers check out:

If you decide you don't need PcAnywhere then check out http://www.virtualscape.com for shared NT hosting.

I recommend: MaximumASP.com and Innerhost.com

oh, yea.. Crystaltech.com as well.

Good luck.

I had a bad experience with CrystalTech.

I put up a satire page that was in poor taste, but clearly not in violation of their terms of service. One of their techs took offense and yanked my account int he middle of the night with no prior notice.

They also refused to grant me access to my site to get my files or the files of my clients. After pursuing legal options to try and retrieve my intellectual property and that of my clients, they informed me that they had deleted all of my content.

Make your own decisions, of course, but my advice is to find someone else.

Peace.

I guess you don't need a dedicated server (otherwise you would have mentioned it). On sharing server I doubt any one will allow you to access the server via PCAnywhere. Rest of your requirements are usual and can be met by most of the hosts. Unlimited bandwidth - be carefull of the hidden charges before signing with any one. All the best.
