I tried to run distribution agent from command prompt, it is the format C:>distrib -Publisher [HOMSAR\WULU2012] -PublisherDB [SVRIADX_C2CSearch] -Subscriber [HOMSAR\WULU2012] -SubscriberDB [subs_coredb_dx] -Distributor HOMSAR -DistributorLogin homsar\repl_distribution -DistributorPassword abc!@# Got error: 2013-09-24 03:40:28.751 Connecting to Distributor 'HOMSAR' 2013-09-24 03:40:46.342 Agent message code 20084. The process could not connect to Distributor 'HOMSAR'. Here I am not sure about some of the parameters: -Distributor - What is the Distributor here, is it the distribution database? the SQL Server instance where the distribution database is on, or the host where the distribution agent is started? -DistributorLogin - not sure what is the Distributor, this parameter is uncertain -DistributorPassword - not sure what is the Distributor, this parameter is uncertain Thanks.
