Performance Monitor Logs Lose Data Across Subnets

ID: Q237579

The information in this article applies to:
  • Microsoft Windows NT Server version 4.0
  • Microsoft Windows NT Workstation version 4.0
  • Microsoft Windows NT Server version 4.0, Terminal Server Edition
  • Microsoft Windows NT Server, Enterprise Edition version 4.0

SYMPTOMS

To connect to a computer across subnets in a multiple-subnet environment with a remote Performance Monitor Session, you must use either the Fully Qualified Domain Name (FQDN), or the Internet Protocol (IP) address. After you connect, you can view data in real-time. However, when you try to capture data to a log, even though the NetBIOS name is resolved and the log grows in size, all objects and counters are lost.


CAUSE

This issue occurs because Performance Monitor is dependent on NetBIOS name resolution when logging data.


RESOLUTION

To work around this issue, use any of the following methods:

Method 1

  1. Place an Lmhosts file containing the computer name and IP address of the target computer in the %systemroot%\drivers\etc folder of the monitoring workstation. View the Lmhosts.sam file for information about how to do so.


  2. Configure TCP/IP to perform a LMHOSTS lookup. For information about how to do so, please click the article number below to view the article in the Microsoft Knowledge Base:

Method 2

Enable DNS for Windows Resolution:
  1. Click Start, point to Settings, click Control Panel, and then double-click Network.


  2. Click the Protocols tab, double-click TCP/IP, and then click to select the Enable DNS for WINS Resolution check box. Note that a DNS server must also be defined in TCP/IP Properties.


Method 3

Point computer monitoring to a WINS server on the network that has the target computer defined:
  1. Click Start, point to Settings, click Control Panel, and then double-click Network.


  2. Click the Protocols tab, double-click TCP/IP, click the Wins Address tab, enter the appropriate IP addresses of the primary and secondary (if applicable) WINS servers, and then click OK.


NOTE: Because the computer performing the data logging is the only one that needs NetBIOS resolution, the quickest way to get the Performance Monitor working is to create an Lmhosts file on that machine. This is not an optimal solution for WINS resolution on a large network because these files would have to be on multiple servers and workstations. Also, IP addressing changes would require modification on all computers that have an Lmhosts file.
