I have this peculiar issue and I have tried several times to work on it nothing seems to be working.
My company databases in SAP business one 9.0PL4 keeps dropping if I anytime restart my laptop.
I often restart my license server and my TAO naming services.
I alternatively uninstalls the server tools and re-install it. Sometimes it appears and if I restart my system(Laptop) they don't appear anymore.
I have done all I know but it is still not showing.
Your urgent help and response will be appreciated.
