Installing SAPOSCOL on a Microsoft Windows
Host
· You have the current version of the file pdh.dll in the System32 folder of your Microsoft Windows system directory (such as c:\winnt\system32). You can find the current version of the file on sapserv<X> in the /general/misc/saposcol/NTdirectory. To do this, start the File Transfer Protocol (FTP) and log on as user ftp with the password ftp.
· You have downloaded the current version of SAPOSCOL as described under Downloading SAPOSCOL.

If you are using Microsoft Windows NT 3.51, take SAP Note 115976 into account.
...
1. If an older version of SAPOSCOL is active on your host, stop this service in the system control and backup the old SAPOSCOL version. On hosts with SAP systems, SAPOSCOL is in the directory \usr\sap\<SID>\SYS\exe\run or \usr\sap\d<inst.no>\exe.
2. Replace this with the new version.
3. Start the SAPOSCOL service again in the system control. If you are installing SAPOSCOL on the host for the first time, set up a service for SAPOSCOL with the following command:
ntscmgr.exe install SAPOsCol -b <path>\saposcol.exe –p service

§ Choose a user for the service that is a local administrator on the relevant server. Only then can SAPOSCOL collect all relevant data. If there is a sapservice<SID> user, use this user.
§ As ntscmgr creates services under the system user by default, change the configuration in the system control after the installation.
§ For more information, see SAP Note 0436186.
You have copied the current version of the operating system collector SAPOSCOL to your host and started it there.
