I've just upgraded my system to PHP4 from PHP3 and surprised - all my old scripts (working good about past half year) says 'No input file specified.'

I use my own web-server Eserv/2.90 (I'm the author) and can give you full information about the way of my web-server running PHP CGI-scripts. It uses 'CreateProcess' function. Command line parameter is "c:\php\php.exe php3.php3", Current dir parameter is "c:\eserv2\wwwroot\shop\" (php3.php3 is in this directory). Environment variables are:
COMSPEC=C:\WINDOWS\COMMAND.COM
GATEWAY_INTERFACE=CGI/1.1
HTTP_ACCEPT=*/*
HTTP_ACCEPT_LANGUAGE=ru
HTTP_USER_AGENT=Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)
PATH=D:\PERL\BIN;C:\WINDOWS;C:\WINDOWS\COMMAND;C:\PROGRAM FILES\MTS;C:\UTILS
REMOTE_ADDR=127.0.0.1
REMOTE_HOST=127.0.0.1
REMOTE_USER=webmaster
REQUEST_METHOD=GET
SCRIPT_NAME=/shop/php3.php3
SERVER_NAME=localhost:3128
SERVER_PORT=3128
SERVER_PROTOCOL=HTTP/1.0
SERVER_SOFTWARE=Eserv/2.90
TEMP=C:\WINDOWS\TEMP
TMP=C:\WINDOWS\TEMP
winbootdir=C:\WINDOWS
windir=C:\WINDOWS

With PHP3 it worked very good (see http://docs.eserv.ru/ as example), but with PHP4 - not :( What I must change to get PHP4 running properly?

P.S. From command.com shell PHP4 executed OK.

Thank you!
