Hi Stefano
Thanks I will try that...because of the issues i had yesterday i googled the errors to see if others had experienced the same problem, and it seems that it could be a DNS issue. This i didnt think was correct. This is a server only sme 8 box for testing purposes inside a sme 7.5 server and gatway network. Our domain is glaslyn.com on the server and gate and i had used glaslyn.local on the test server (glaslyn is welsh for blue lake by the way). This morning trying to log onto the main server I had an issue with password recognision from a client machine. This does look like a DNS thing.
So i have re-installed the server only software, mainly because using - yum erase postgres* - I think may well have removed other stuff also. I have also changed the domain to something else, by way of a test, and this morning will endevour to install Postgres yet again.
Thanks Bluelake
