netxms is very useful tool, but it's also silly on other hand. 
I was able to log in, and it was working fine. 
Once i rebooted my commits stoped working (connection refused)
			
			
			
				Check your services and make sure they are set to start; check server log for errors, etc.  
			
			
			
				
but if i re-install,  than works well.
That tells me that something isn't right with the app itself
			
			
			
				can i get any thoughts pls
			
			
			
				Pls give some details. 
Is you NetXMS installed on Windows or Linux?
Do you use WEB UI? Have you tried the desktop UI?
