Timeout issue with GetChildItem

I wrote a script to remote 500+ 2k3/2k8 servers for specific files with get-Childitem. It first check if the file exits and if the patch exits. The status is logged in one file and the result is logged in another file.

For some reason I am not getting any result back.

1.If I run one individually, it works and I see the search results.

gci -Pa \\serverA\d$ -In access.log error.log -Re

Select allOpen in new window

2. I got many "specified network name" errors, but obviously machines are online if I do a dir
\\serverA\d$.

Get-ChildItem : The specified network name is no longer available.
