It is possible that the target host has a firewall and has blocked the ICMP response.

Smartdrv.exe load the disk cache, the parameter is the size of the cache, in kilobytes.
such as: Smartdrv 32768 is the load 32M cache.
The role of caching is obvious when you install Win2K! No cache loading Win2K Pro takes about 3 hours, after loading 8M cache, as long as 30 minutes.
The principle is that an area is partitioned in memory, and the data on the hard disk is continuously read into that cache area during installation, making full use of the memory.
