ok I'm sure this is a simple stupid thing but I've never done it before so I want to get it right. I don't believe my network is syncing with a time server. we're about 5 mins off. I want to get the clocks to sync but I'm not really sure how. I know there are public time servers out there that I guess I could use? Could soemone give me a little guidance? I think the timing issue is causing some weird security issues on my servers so i'm hoping this will fix it. I'm a pure windows shop by the way. thanks!

Pretty comprehensive article here:
http://blogs.technet.com/industry_insiders/pages/w32-tm-service.aspx
There are links to MS articles as well.

If you have a domain the PDC should be the time source, that's the one you want to set up to sync with an external source.  The rest of the computers should sync with it by default.  
List of NTP servers: http://support.microsoft.com/kb/262680 this may be dated, you can just google LIST NTP SERVERS and find a more current one if necessary.

A good source of info is the NTP project. They provide pools of external time sources.

Furthermore, you need to make sure that the NTP protocol is allowed to travel through your firewall (UDP/123)

the command you are after is:
 
net time /setsntp: <list of servers>
 
there are public NTP servers available. Google a list but usually your ISP will have one you can use. If you set your PDC emulator to use an external source the rest of the domain will sync to it (DCs to PDC and member servers / clients to DCs)
