Unable to connect to companyweb from outside of office

I had to reinstall Server 2003 Small Business and since, have not been able to connect to my companyweb.  I can connect to remote workplace and can get on the server or any of the client computers remotely, just not companyweb.  I get a simple 'unable to connect to website" message.  Whether it is important or not - but I notice the link to get to the companyweb begins with https://online.xxxx.net:444 whereas the link to remote workplace is https://xxxx.net/remote.  I can access Outlook Web by typing the cwww.companysite.net/exchange.  And whether it is related or not, since the reinstall, my windows mobile phone will not connect & sync wireless with my outlook.
