Solved?? : Can only use server hostname

I have just created a table based custom login page and everything works great as long as I use the Server hostname in the URL. I am setting up a DNS from outside and if I try to login using this URL it will not work. It will also not work simply using the IP Address as the URL.

I initially thought that I had hardcoded some PHP to look at the hostname specifically, but I have searched the entire site and there is no reference to the hostname, and only one reference to the IP address in the connection include.

Any help is greatly appreciated.

------------------------------

Update : I just did some testing and the problem is much stranger than I initially thought. The test server is 2K3/IIS/FMSA. I am coding remotely and uploading files to the server across a VPN from a non-domain PC. Since I am not resolving DNS to the customer site I simply created a host record on my pc which is just the hostname of the PC (faxserver) and the IP. From my PC at home everything works using the hostname, but I can not use the IP address. From ANY other computer including others at home or any onsite which are local to the test server the login will not work.

You can see the initial login screen, but it just returns you to the same index.php file with no error message. Obviously this is some kind of DNS issue, but I can't even imagine what it could be. As I stated before none of my code explicitly looks to "faxserver", and even if it did I can access the login screen using http://faxserver from every PC on their network, but I still can't login.

BTW : I can't even login using the test server, but I can from a PC across the VPN!! I have tried http://faxserver, http://127.0.0.1, and http://192.168.111.249 to no avail. I have also cleared out both browsers cache and get the same problem.

--------------------------------------------

Latest update : Just to see if it was something weird with the host entry I duplicated it on the server and it did not work. I also removed it from my PC and as expected I could not access the server with the host name. It seems the ONLY Pc that can login is mine. I am going to try changing my IP as well as pointing to the customer server for DNS to see if this fixes the problem, but I don't expect it will. I have searched all of my code with Dreamweaver and there is only one reference to an IP and no references to any hostnames of the involved servers/clients. The only ref to an IP as mentioned before is the connection PHP include.

I am totally lost!!

Well, I found a "solution" to this today but hopefully someone can explain why this may be happening.

I will create a new thread entitled Table Based Login Issue for the sake of clarity on the issue.
