log in problem

Hi..

I have been given this problem to troubleshoot but I am not very familiar with the Internet Infomation Services (IIS) or firewall setting so if someone can guide me whould be great.

We have this log in asp website which can be accessed through Intranet and I have tested there is no problem. But this client needs to log in to our site from her company but she cant log in. From our company when log in using her account using the intranet link, I can logged in. However I cannot log in from external link which our client uses to log in from her company. So I tested that external link from my home which is the different isp from my office and it works.

So far I have asked her to try to log in in different computers in her office and told her to make sure her browser to accept cookies. She still cannot log in.

Now what should I do. I think I need to check our firewall to see why I cannot log in to the external link from our company and why she cant log in from her company. Where can I check to see her company ip address could be denied?I think i need to check in ISA and IIS setting but I dont know how. Please help me.

thank you in advance.
