RF's can't connecting to terminal server.
Hello,
I having trouble with my new terminal server. I am using RF's (intermec & motorola) in my business and We have two terminal servers that is running with 2008r2 standard. RF's can connect to first terminal server unproblematic but can't connect
to other one and getting error as "Because of a security error, the client could not connect to the remote computer, verify that you are logged on the
network, and then try connecting again"
I can connect to all terminal servers with my domain computer via remote desktop connection.
Own enterprise network has PEAP-WPA2 user authentication
Rf's are not in the domain.
I need help from you.
Thanks.
Hello everyone,
We found a solution regarding this case with microsoft team. Solution is in the following.
Issue Statement:
Cannot connect RF scanner to a particular server using RDP.
Symptoms:
> The RF scanners are Intermec CK3R devices with windows embedded handheld 6.5 classic installed on them. They fail to connect to
a particular server using RDP. However, same user and device can successfully connect to another server. The server to which the device fails to connect is TRKKTA01-N.
> Never been able to connect to the problem server.
> Both the good and the bad server are Windows 2008 R2.
> The Devices are connecting using per user licenses.
> We can connect to the problem server using a Fat client like Windows 7 machine with the same user ID.
> both the Problem server and the working server are in the same network but on different VLANs.
> On the Scanner, when trying to RDP user gets the following error:
"Because of a security error, the client could not connect to the remote computer, verify that you are logged on the network, and
then try connecting again"
> Already different encryptions have been tried but the connection still fails.
Environment:
RDS server is Windows 2008 R2. Clients are Intermec CK3R devices and OS is Windows embedded handheld 6.5 classic.
Scope Agreement:
We will close the case once we find the cause of the RDP failure and provide a possible fix for it.
If the problem is found to be due to third-party code we will provide information to substantiate this.
Case Status: Resolved.
Steps used to resolve the issue were:
1. Create the following reg key on the license server:
Use512LenPropCert on the Server
Subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM
Registry entry: Use512LenPropCert
Data type: REG_DWORD
Value: 1
2. De-activate the license server
3. Re-activate the server using the telephone method
4. Delete the x509 cert keys from the terminal servers
Best Regards,
Ufuk BAYGIN

Can't connect to terminal server via Mac RDC
Users can't log in to our terminal server (Server 2008) from Mac using RDC 2.1. After typing in the server name, the client asks the user to login. The user fills in their username, password and domain but receives and error stating "The credentials
that were used to connect to [server_name} are incorrect".
Any user, including myself who am a Domain Admin, get this error. When I log in using the domain's Administrator account, however, I can log in just fine.
None of this occurs when trying to login from a Windows client. The Mac I tested on is running OS X 10.5.8. Any help would be greatly appreciated. Thanks.Hi,
For remote desktop in MAC OS, you can try to update the new Remote Desktop Connection. New Multiple Session Support gives Mac users simultaneous access to multiple
Windows-based PCs or to a network server that hosts remote applications and files. Since it is a Universal application, Remote Desktop Connection Client 2 is compatible with the latest technologies on Windows and Mac platforms.
Please refer to the following link:
Microsoft Remote Desktop Connection Client for Mac 2.1.1
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=18140
Setting 'Allow connections from computers running any version of Remote Desktop (less secure)' in the Terminal server to sees if it’s work well.

Safari can't connect to the server - still causing problems
Hi
I have read through several topics relating to this problem - but have yet to be able to resolve the issue. So apologies in advance if it has already been answered in one of the many threads.
I have 2 computers both working off the same broadband hub connection.
Both have the same version of the OS and the same version of Safari: OS 10.4.11 and Safari 4.0.4
I have checked that the network settings are the same and all parental control settings are the same.
The laptop will access sites that the desktop will not.
Can anyone shed some light as to why numerous sites I try to access on the iMac result in a Safari message "Safari can’t connect to the server".
Same applies when I attempt the same sites with Firefox.
I have emptied caches, resolved all font issues, addressed terminal and plists etc. etc. - all to no avail.
Help!!!Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security:
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:
http://support.apple.com/kb/TS2296
If your computer is part of a network: please refer to this page: http://www.opendns.com/start/bestpractices/#yournetwork and follow the advice given.
You could also try these codes as well: 4.2.2.1 & 4.2.2.2
If you use a Router, make sure it has the latest firmware installed. -
ERROR#: 2002 can't connect to MySQL server through socket '/var/mysql/mysql.sock'
I was following this adobe article (
http://www.adobe.com/devnet/dreamweaver/articles/php_macintosh.html)
to set up PHP and MySQL and connect a MySQL database to dreamweaver
in Mac OS 10.4.8 and I kept getting:
"Can't connect to MySQL server through socket
'/var/mysql/mysql.sock' ERROR#: 2002".
After a lot of searching I came across
this
article which said that there was an error in the PHP and MySQL
connection or something.
Anyway all I had to do was type (in a TERMINAL window):
$ sudo mkdir /var/mysql
$ sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock
and that fixed the problem, otherwise the adobe article
worked very well.

Error: Can't connect to auth server at /var/run/dovecot/auth-master: No su
Error: Can't connect to auth server at /var/run/dovecot/auth-master: No such file or directory
error showing up, there is no auth-master file in /var/run/dovecot
this has just happnened over night
any ideas how to re-install dovecot
google search goes on about linux but barely any info about max osx serverauth-master is created when you start the mail service. Deleted if you stop the mail service. If that is not happening, you may have to re-install mail. Dovecot is the IMAP/POP part of the mail service. I am not sure what happens if you disable IMAP. I am guessing it is not there. But that is the extent of any tips I can offer. I suppose you could reinstall, but that seems a bit extreme to me.

Dear Fellas:
I received "database error #2002 can not connect local mysql server to socket through '/var/run/mysqld/mysqld.sock'(2)" on mac os x 10.9.2.
mysql info:
ps -ef | grep mysql

501 952 947 0 3:52PM ttys000 0:00.00 grep mysql
Please help!!Fascinated and guessing:
Something related to sock(2) because that's not part of your copied info. I'm thinking you've doubled up on sockets and the second socket doesn't exist, meaning you should be connecting to the first socket "mysqld.sock" whether automatic or not.
I've only used GUI tools on purpose, so does this mean you've already got MySQL running and you tried to launch it again manually? Perhaps you already have one instance of a db and you're trying to launch a second instance, and the two can't coexist with a single user local db?
Assuming this is all local, I'd shut down the db service and restart it, out of hand. I've seen similar messages when I set the db to start up on boot, and it didn't finish shutting down when I tried to restart it manually. Usually the GUI won't let me turn it on because it reports it's already running, but in that case it hadn't finished performing what the GUI was reporting.
Just speculating. -
My ipod touch connects to wifi but can't connect to the server.
Ok, so my ipod youch says it's connected to the wifi but when i try to get on the internet it says it can't connect to the server. I've looked and there's alot of answers but they're all soooooooooooooo complicated. I'm like 14, so whoever can answer this, please use small words.
I've noticed in alot of the answers they talk about your IP adress, if it's any consilation mine starts with 169. No matter where I go, if it's at home, or at starbucks or a hotel.
Thanks for your timeHave you tried restoring your iPod touch in iTunes?
You may just be trying to connect to "Printer Networks" that allow a company/residence to print something from their printer wirelessly, it would appear on your iPod touch just about the same as any other network, but you wouldn't be able to use internet while connected to that network...
If you are talking about "free wifi" in a Cafe, like Starbucks, you will usually need to open Safari. A Page will load and tell you how to connect to their internet, whether it's by paying, or just agreeing to their terms...
Like, I said, if that isn't the problem, try restoring your iPod touch in iTunes...

Safari Not Loading Web Pages (Safari can't connect to the server)
I'm seeing increasing problems with Safari being unable to connect to websites. When the problem starts to manifest itself you see the error:
Safari can't connect to the server.
Safari can't open the page.
Then you see the URL information. It is always seems to be sites that are trying to load HTTPS pages.
Clearing the cache and resetting Safari will make it go away temporarily, but it always comes back.
Note that when this happens you might happen to see something like this in the address bar:
file:///Applications/Safari.app/Contents/Resources/I'm having the same problem, I can open safari but when I try to go to a website it just says "server stopped responding." I just updated to the new version and that's when it started happening, it was working find before the update. Any suggestions???
