Allright. We are a company of around 65 people. We will be implementing EX2003 very soon. We have our test network up and all is happy (barring some minor bugs). But, now we are looking at putting the EX2003 server into the DMZ to allow people outside the company to use thier email. Now...

We are running DNS for our building on a Windows 2003 Domain Controller. It works great most of the time, but about 1x a week, it no longer resolves external addresses (yahoo.com) but it does a dandy job on internal ones. Any ideas, anything you want me to post?

Whoa! Call me a total noob, but isn't the NET USER, NET GROUP and other such commands a tremendous security problem in an Active Directory Domain? Out of the box, any computer/user joined to the domain can do some pretty nifty things... Like ADD THEMSELVES TO THE DOMAIN ADMINS GROUP! That's...

I've got a few problems, and I think they all stem from the same source, which I can't seem to track down. We have a small 2003/2000 network. Our PDC is the 2003 server. It is also the DNS and DHCP server. There is a 2000 server that acts as a BDC. It is only being used as a file server and...

We have a Parent domain : company.com a child domain: child.company.com They have the 2 way trust set up and has been validated. However, if I set up a user on company.com, and try and log into child.company.com with the user's credentials, It does not authenticate. This also happens in the...

I have read two solutions for changing the domain name on a Windows server 2000 system. One requires the use of an NT4 box that replicates the AD then gets promoted. The other solution (the one most preferred by MS) is to upgrade to 2K3 and use the Domain Name Change Tool. Our company is...

We have just implemented a new network involving a PIX 515e and a Catalyst 3550 switch. The network swap went well, and the network is running smooth, for the most part. Occasionally, a (only Windows so far) computer on the network will loose internet connectivity. They are able to get DNS...

I had this posted in the Win 2K forum, but I think the topic has drifted into this forum's scope. I am re-engineering the network topology in my organization and I have decided on creating multiple segments (subnets) with a single DC, DHCP, DNS server serving all the subnets. I understand that...

All right. I'll try and explain this as succinctly as I possibly can. Our organization has reached a point of reorganization and we are exploring options for our internal network structure. We currently have three subnets (10.2.x.x, 10.3.x.x, 10.4.x.x). Each one is running it's own DNS and...
