Yes, Microsoft provide a Windows 2003 Resource Kit which has a DOS like command similar to the *nix grep .

Here is a brief of qgrep provided after you have installed the kit.  Click here to download the resource kit or visit here and search for "Windows Server 2003 Resource Kit Tools" if the first options were unavailable.

qgrep /?

usage: qgrep [-?BELOXlnzvxy][-e string][-f file][-i file][strings][files]
-? - print this message
-B - match pattern if at beginning of line
-E - match pattern if at end of line
-L - treat search strings literally (fgrep)
-O - print seek offset before each matching line
-X - treat search strings as regular expressions (grep )
-l - print only file name if file contains match
-n - print line number before each matching line
-z - print matching lines in MSC error message format
-v - print only lines not containing a match
-x - print lines that match exactly (-BE)
-y - treat upper and lower case as equivalent
-e - treat next argument literally as a search string
-f - read search strings from file named by next argument (- = stdin)
-i - read file list from file named by next argument (- = stdin)
White space separates search strings unless the argument is prefixed with -e, e.g., 'qgrep "all out" x.y' means find either "all" or "out" in x.y, while 'qgrep -e "all out" x.y' means find "all out".
