title: BizTalk SSO Configuration - There are no more endpoints available from the endpoint mapper
body: <p>I have a two node BTS2010 group with a separate SQL Server hosting the BTS databases including SSODB; Biz01, Biz02 and Sql01. This environment was configured by a previous employee and I have no documentation available.</p>
  
  <p>There seems to be something not right with the SSO config but I'm not sure how to resolve it.</p>
  
  <p>When I run ssoconfig -status on Biz02 all looks good - it tells me that the SSO Server is Biz02 and the SQL Server is Sql01 plus a load of other stuff. However, when I run the same command on Biz01 I get the message: "Error 0xC0002A0F: Could not contact the SSO server 'Sql01'. Check that SSO is configured and that the SSO service is running on that server' 
  
  <p>I'm not clear on what Biz01 is trying to do here - is it trying to reach the EntSSO windows service on Biz02 via an RPC call, before ultimately attempting to retrie config info from Sql01?</p>
  
  <p>I have checked that the ENTSSO service is running on Biz01, Biz02 and that the RPC service is running on each of the three servers.</p>
  
  <p>Can anyone help advise what further steps I can take to determine the root cause of this configuration problem?</p>
  
  <p>Many thanks</p>
  
  <p>Rob.</p>
