HP -UX B6941-90001 Administrator's Reference Manual page 171

NOTE For Windows NT managed nodes running Service Pack 1 or 2, the
communication type must be changed from DCE UDP to DCE TCP to
avoid problems.
If you decide to change the communication type, you must update the
ITO agent software:
1. Ensure that your managed nodes meet the software requirements
described in Chapter 1 of the HP OpenView IT/Operations
Administrator's Reference. In particular, ensure that the required
DCE RPC software is installed and that the DCE daemon is running
if you switch to DCE RPC.
2. Stop all ITO agent processes, enter:
/opt/OV/bin/OpC/opcragt -stop
3. To change the communication type, you choose between the following
methods depending on the number of managed nodes you want to
modify:
If you want to change the communication type for only a small
number of nodes:
a. In the ITO administrator GUI, select the managed node in the
ITO Node Bank for which you want to change the
communication type.
b. Select Actions: Node -> Modify.... The Modify Node
window opens.
c. Click on [Advanced Options], and change the
communication type in the Node Advanced Options window.
Select one of the following options:
• DCE RPC (UDP) (recommended)
• DCE RPC (TCP) (useful when communicating over a WAN)
• NCS RPC
d. Click on [OK] in the Node Advanced Options and the
Modify Node window.
If you want to change the communication type for a large number
of managed nodes, you can use the ITO tool opcnode. The easiest
way to do this is to add it as an ITO application to the ITO
Application Bank:
