errors while installing exchange

While trying to install Exchange enterprise edition onto NT server 4. I get a number of error messages towards the end of the install process, while registry changes are being<br>made. It goes as follows with these exchange server setup messages :-<br><br>*********************************************<br>&quot;The command 'lodctr dsactrs.ini' failed returning an error<br>code of &lt;32&gt;&quot;<br>*********************************************<br><br>press OK and another one appears.<br><br>*********************************************<br>&quot;processing file 'd:\server\setup\i386\server.ins' at or <br>near line 153<br><br>An internal component has failed<br><br>Microsoft Exchange server setup ID no: c103798c&quot;<br>*********************************************<br><br>press OK and the last one comes up.<br><br>*********************************************<br>&quot;An internal component has failed<br><br>Microsoft Exchange server setup ID no: c103798c&quot;<br>*********************************************<br><br>press OK to this and the setup process terminates without exchange being installed, although files are dumped on the hard disk<br><br>I've examined technet and can only find this error message referring to other lines in the server.ins file and a fix that doesn't work relating to perfc009.dat and perfh009.dat files.<br><br>Does anyone have any ideas as to the cause and possible resolution ( I've tried re-installing NT server so that didn't work. I can't see that putting exchange enterprise onto NT server should be a problem either ).<br><br>thanks in advance<br><br>Mike<br><br>
