My hp laserjet 4100mfp didnot scan and email the document. it show error on display that no send opptions available. I already config the smtp default gatway.

It sounds like you need to reinstall the driver and application software and ensure that the unit is configured to scan and send. These are options when you do the initial installtion. This should give you application icons on the PC.

Recovery CD not loading onto Hard Drive.

Your optical drive is not reading the disk properly - a common issue as time goes by. Replace drive with a good known working unit and your recovery operation will take place.

C0000139 Entry Point not Found computer will not boot-up.


Are you getting this error with RPCRT4.DLL. If you do you need to replace this file from the Xp disk.
If you cannot follow, send me a message at and hope we can talk over gmail or skype and i'll guide you through.

It may be difficult for you to do it.But if you could do, here the steps are :--
1.Use the Windows XP Recovery Console to replace the RPCRT4.dll file with the original version. To do this, follow these steps:
Insert your Windows XP CD-ROM into the computer's CD-ROM drive or DVD-ROM drive, and then restart your computer from the CD-ROM.
Some computers may require that you modify the basic input/output system (BIOS) settings before you can start the computer from a CD-ROM. For information about how to modify BIOS, see your computer documentation.
At the Welcome to Setup screen, press R to start the Recovery Console.
Press the number key that corresponds to the installation that you want to repair, and then press ENTER.
Type the Administrator password, and then press ENTER.
With the Windows XP CD-ROM still in the CD-ROM drive or DVD-ROM drive, type the following commands, pressing ENTER after each command:
cd system32
ren RPCRT4.dll RPCRT4.old
cd \i386
expand RPCRT4.dl_ BootDriveLetter:\windows\system32

It'll fix your problem. :-)

The monitor reads: system boot failure. Insert recovery disk.

McAffee Security or adding memory cards should not effect the ability to do a system recovery, but so be it. Here is a list of presario laptops, do you know which is yours?

Can't extract files on System Recovery Disc 4 for Compaq Presario model 6350US

At this point, you can try to clean your disk # 4 and see what happen,
or try to make a copy of disk # 4 (if you can copy the disk) and try again.


1) Contact your customer support and ask for a new set of disks.(or only # 4)


2) Boot your computer with another OS disk (win XP)


3) Boot your computer with some utility disk

I want to re set up my compaq presario 900

Hi, I checked my rpcrt4.dll, it is a 5692 kb, a check on the web says it is originally a 323.2 kb file Remote Procedure Call Runtime, v. 5.1.2600.1106 available for download at I believe it can also be extracted from the I386 folder of your XP installer CD. If your system will not boot fully, try F8 to boot in Safe Mode. Perhaps it may be worth your while to also do a full scan for viruses or ads/malicious software of your HD. Hope this work out for you. Post back how things are or should you need further information. Kind regards.
