Troubleshooting

Grouping Manager

Problem: Cannot import users from NT Domain Controller
The EPICenter Server must be running with permissions that enable it to get user information from a
Domain Controller. To verify and change permissions for the Web Server, do the following:
1 From the Start menu, highlight Settings, pull right, and click on the Control Panel. This displays the
Control Panel folder.
2 Double-click on Services to display the Services Properties window.
3 In the Services properties window, select EPICenter 4.1 Server and click Stop. (To find the Services
window, from the Start menu select Settings, then Control Panel, the double-click the Services icon).
4 When the EPICenter 4.1 Server service has be stopped, select it again and click Startup.... This
displays a pop-up window where you can specify start-up options.
5 In the lower part of the window, in the Log On As: area, enter the account name and password for a
user who has the appropriate permissions to access the Domain Controller.
6 Click OK to restart the Web Server service to have the new user logon take effect.

Printing

Problem: When printing a topology map from the browser client, or a printing report, the browser
can appear to freeze.
Printing a report or a topology map can cause the browser utilization to become very high (approaching
100%) and can spool a very large amount of memory. There is no current solution other than to wait,
and the process will eventually finish.

Topology

Problem: In Map Properties, changed the node background color, but only some of the node
backgrounds changed.
The background color affects submap nodes, device hyper nodes and device or decorative nodes that do
not display the device icon (either because the icon display is turned off or the nodes have been
reduced in size to where the icon cannot be displayed). For device nodes and decorative nodes with the
device icon displayed, the background color is transparent, and the background color setting is ignored.
Problem: A link has been moved, but the old link still appears as a down or unknown link. In
addition, if just one end of the link has been moved, an L2 cloud node is added between the two
endpoint devices.
When a previously "up" link disappears, the EPICenter server cannot tell if whether it is down or has
been physically moved, so it changes its status to down (or unknown). EPICenter will detect the new
link and add it as an up link, but it will not remove the old link. If only one end of the link is moved,
EPICenter detects two links (one up and one down) that share the same endpoint on one side of the
link. It interprets this to mean that there is a hub between the two endpoint devices, and represents this
as an L2 cloud.
