This might give the clue why the repos corruption is much more
likely on the P4 machine than on my old P200 notebook: the P4
has 1 GB pagefile, the notebook 460MB only. On the notebook
more virtual memory gave me the overall impression of slower
operation, 460MB seemed to be a good value though. In the setting
dialog Win2K recommends 216MB only, however, else it is said to
set 2.5 times of RAM and others suggest taking 4GB if available.
Of course the P4 shall become the server - if I ever get into
production again! ;-) T
