hi. i've asked this question probably three times, but have yet to figure it out. i'm a little closer but still not sure if i'm missing something. currently there is http://www.mydomain.com/ i want to add http://dev.mydomain.com/ . i have already added the sub-domain in iis and pointed it to a directory on the local hd. i also put a index.asp file in it to make sure it works. in my previous email i noted that i only wanted this to work internally and not be reachable from the outside world. i was instructed to modify my HOSTS file with a line like this... <ip_address_of_machine> dev.mydomain.com i've tried both the external ip address and the internal ip address. we run our network on a 10.x.x.x ip scheme. if i am at my workstation (seperate from the website box) and type in http://dev.mydomain.com/ i am greeted with the equivalent to http://www.mydomain.com/. i did a little experiment and modified the HOSTS file of the website box like so... 127.0.0.1 dev.mydomain.com which gave the HOSTS two records. all of which looked like... 127.0.0.1 localhost 127.0.0.1 dev.mydomain.com when i try to access http://dev.mydomain.com/ on the website box i am greeted with the index.asp file i created. (although it should be noted that even though i have specified a <title></title> in the index.asp file, the browser says Cannot Find Server/Cannot Find File Specified [i don't remember exactly which one] in the title bar.) it looks to me as if what i'm doing is going to take a little more configuration to work on a remote machine. so my question is... without external DNS changes and/or changes to our NAT table, will i be able to remotely (although internally) access http://dev.mydomain.com/ or will i have to be on the local box for that to work? thanks, chris.
