sharepoint and server certificate

In order to make the sharepoint services I set up on our server become public, so other people ca participate in the conversations, it is saying that I have to acquire a server certificate.

I've been told that i could use a self signed one but that it won't work across all browsers.  However, I find this hard to believe because Sharepoint services comes free with my windows 2003 server and in all the sites I've been to that instruct on how to install and use Sharepoint, none have mentioned anything about having to purchase a server certificate.

Can anyone shed some light on this for me please?

i didnt have a problem with self signed certificates and SBS2003

you can import the certificate to your browser to get rid of the warning

but i just moved to Win7/Office2007 and my outlook (using rpc over https) still complains about the certificate, but works well after klicking the message. maybe i have to google that :-) they might have changed something

but to come back to your question, if you want to have an official certificate, the prices differ much between the providers. one said, that godaddy is a cheap provider.

It wouldn't be a problem for me to have to click thru an error message if that's all that is needed, but the other people that will be using it (our other users and clients outside the office) won't want to deal with this.  I'm still looking for a solution, but if you (or anyone else) knows a way to just create our own certificate and use that, I would love to hear about it.
it is really not a problem to use a selfsinged cert. but all users, accessing your site will get this message. this is, because, the browsers dont know you as trusted ....dont know the word in english....."organisation"

so, if you dont want the users to get this message, you can import the cert to all the clients browser to tell them "trust my cert" and the message is gone. but this wont work, if you have external users and maybe they change over the time.

so you will have to buy an official cert, if you dont want this warning. that will known by internet explorers or firefox as trustfull. and there will be no message.

i think godaddy is 30$ per year...but i didnt try it myself....youst heard about it
