SharePoint Tips for the day
Posted by hema2009 on September 28, 2009
1) If you place a query server beyond a firewall from its index server, you must open the NetBIOS ports (TCP/User Datagram Protocol (UDP) ports 137, 138, and 139) on all firewalls that separate these servers. If your environment does not use NetBIOS, you must use direct-hosted server message block (SMB). This requires that you open the TCP/UDP 445 port.
2) If you want to have more than one index server in a farm, you must use a different Shared Services Provider (SSP) for each index server
3) You must install Office SharePoint Server 2007 on the same drive on all load-balanced front-end Web servers.
4) In farms with more than one index server, you should stop the Central Administration service on all index servers. This service is used for the Central Administration site and is not required on index servers. Stopping this service on index servers can help avoid URL resolution problems with indexing. On the other hand, you must be sure that this service is started on the server that hosts the Central Administration Web site, even if that server is also an index server. You do not need to stop this service for installations where the farm has only one index server.
Before stopping the service on the index server, make sure that the service is running another server.
5)The account we use to propagate the index must be must a member of the Administrators group and a member of the WSS_ADM_WPG group on the query server before you proceed to the next step or propagation of the index will fail. Refer this Link
