Master Slave (active passive) configuration

You mean some kind of server load balancing?  I believe you'd have to use Microsoft's Cluster Server found at:  http://www.microsoft.com/windowsserver2003/technologies/clustering/default.mspx.  Windows 2000 can also do clustering.

Alternatively, there are network solutions which can do server clustering.  Cisco's http://www.cisco.com/warp/public/cc/so/neso/ienesv/cxne/cslbs_ov.htm

Nortel's:  http://www.nortelnetworks.com/products/01/alteon/2224/faq.html

We use Radware Web Server Directors:  http://www.radware.com/content/products/wsd/default.asp

HTH

The set up is as follows there is a Master machine that serves up all the web content and has SQL server installed the second machine is simply a copy of the first and only becomes active in the event that there is a problem with the master.

windows 2000 is installed on box boxes

I hope this helps

i think he is asking which network protocols must be allowed between 2 servers if they are in  a cluster in order for them to work.  Is that the case?

mikeleebrla that is what i am asking thanks

Check out this page: http://www.microsoft.com/windows2000/techinfo/planning/clustering.asp

They could also refer to FTP kind of access which can be passive and active. Check this link http://slacksite.com/other/ftp.html - as you are new to networking, you might not understand it fully; let me know if you need a much more "accessible" explanation. However, the bottom line is that for security reasons it is better to use a passive access.

Anyway, my explanation doesn't "click" with the "microsoft protocols" part!!! Protocols are usualy defined as standards and are not (usualy) from microsoft! However, they are indeed the "authors" for some authentication protocols and some other own additions on other protocols... I'm not even trying to search by brain now about what are these protocols anyway ...

Cheers.
