D-Link DP-300U My brother gave me this equipment, he forgot the password. Used psadmin, but can't reset without password.

Unfortunately, I don't know of a way to manually reset this without using the web-interface.

However, if it was somehow reset already, the default password for this unit is nothing. They do not use a password by default, so try it without one.

Good luck!

Reset button is in back panel of printer sertver.
Press it for 10 seconds.
Then all settings goes to defaults.
Reset button is small round in back side of router you can press it's pin with any ball -pen.

Better way when you take new dp 300u unit in box cd in cd admin software run you can reset button is there please check

Try using the psadmin software to do a factory reset. If it demands a password to do this, try using "SYSxxxx" (where xxxx stands for the last four digits of the MAC address written on the underside of the server. If you don't have the psadmin software you may be able to download it off the internet. After doing the reset you will need to follow the Quick Install Guide to set up the server. If you lost the Quick Install Guide you can download a new one from D-link's website. The following link may also be helpful: http://www.fixya.com/support/t224263-dp301p_psadmin_password_forgoten

You may use the PSAdmin software to configure your print server even if you don't know the IP address. The only requirement is that the DP-300U has to be in the same network (subnet) as your PC running PSAdmin. In the PSAdmin, you will then be able to view or change the IP address.

Here is the link to download PSAdmin:

Remember that if you also have forgotten the Admin password, you will have to ship the unit to D-Link in order to have it factory reset.

Reset The Printserver from Backside & Gave PAssword again

Problems with your D-Link DP-300U LOST IP If you’re like me, you have a ton of computer **** laying around your house. Today I found an old D-Link DP-300U print server laying around and thought that I could put it to good use. The bad thing about these things is the fact that they do not have a hardware reset button on them, so if you forget the IP or the Password, you’re pretty much hosed… or so I thought. After doing some google searches for how to find a lost IP, I came back empty. The PS Admin program that D-Link publishes for use with this thing couldn’t find it on my network either. After some thinking, I came up with an idea.
If you know anything about networking and how networks work, you should have thought about this too. Get a Wireshark capture running. Unplug the power from the print server and then replug it. It’s going to send out an ARP on the network looking for it’s gateway which should be picked up by Wireshark. It should look like this:
In my case, it came back as 192.168.1.253. After changing the IP on my laptop to fit that subnet, I was able to log into it via it’s web interface (there was no password on it thank God!) and put it back to factory settings. Voila! What once was a brick is now a working print server!

I Copied it!

viaujocposted a brilliant solution which worked for my DP-300U: see http://www.fixya.com/support/t224263-dp301p_psadmin_password_forgoten

To paraphrase,
First try logging in with the following
username: psadmin
password: SYSXXXX
(where XXXX is the last four digits of the mac address)
If it works, you can proceed to reset the password.

Alternatively, you may be able to extract the original password from a configuration backup, if you have one. For details, see http://www.fixya.com/support/t224263-dp301p_psadmin_password_forgoten
