This chapter covers:
checking the Windows Event Viewer for obvious problems,
resolving problems related to setting up 3Com Network Access 
Manager.
Checking the Event 
Viewer
If you experience network access or RADIUS authentication problems on 
your network, first check the Windows Event Viewer to see whether the 
problem can be readily identified and corrected.
Follow these steps:
Select Control Panel>Administrative Tools>Event Viewer.
Select System from the Tree pane, and review the events in the log in the 
right hand pane, see Figure 29. IAS in the Source column indicates an 
event was generated by IAS. Use the information in the log to determine 
the reason an IAS connection attempt was either rejected or discarded. 
Click on any event to display more information about the event.
Select 3Com Network Access Manager from the Tree pane, see Figure 30. 
Review the events in the 3Com Network Access Manager log to 
determine whether 3Com Network Access Manager has been set up 
correctly. Click on any event to display more information about that 
event, Figure 31 shows computer ‘S4400-45080’ granted network access 
to VLAN 2 with QoS Profile ID q2.
