HT1595 I am not able to connect from my laptop to airplay mirroring equipment, icon is not showing on my laptop.

I am not able to connect from my laptop to airplay mirroring equipment, icon is not showing on my laptop. It does show when I hook up a HDMI wire to the apple TV box.

I think you mean Ethernet, not HDMI wire. If the airplay icon is showing up when wired then that would indicate an issue with your wifi network.

Apex link not able to connect from local machine.

Hi,
Here is the scenario.
I have installed oracle apex 3.2 in my vmware linux machine.
I'm able to connect the link (http://b03apex.domain.com) from my linux(vmware) box but I'm not able to connect from windows local machine.
I tried to ping the ip, from both the ends are working but not sure why I'm not able to connect from windows local machine.
local windows ip: 192.168.1.2
vmware Linux ip address : 192.168.1.3
Do I need to do add any parameters in the Apache logs to connect from windows local machine.?
Need your suggestion.
Thanks, Muhammed.

Can you ping the VM hostname from your Windows console (instead of IP address)?
Have you tried in your Windows browser the following URL (using IP address of the VM instead of the hostname)?
http://192.168.1.3/
Have you checked that your browser is not configured to use a proxy server?
Have you checked your Windows firewall for allowing tcp web traffic to the virtual machine?
Have you checked for the same on on the virtual machine (firewall will be likely be done using <i>iptables</i>).

Since tnsping did NOT return an error, we know that you did not tnsping 'orcl', which is what you tried to connect to with sqlplus. Show us the actual tnsping command.

I'm not able to connect from 9.2 client to 8.1.7.0 database through ODBC

Hi,
I'm trying to connect from ORACLE 9.2 client to 8.1.7 DATABASE. The client is on WINDOWS XP. But I'm getting connection timed out error message. What's wrong with that ?

Can you connect to the 8.1.7 database from other clients? Can you verify that the listner is up?
Can the 9.2 client connect to some database?
I'm guessing that the 8.1.7 database listner isn't up or that the tnsnames on your client isn't set up correctly.
Justin Hi Justin,
1) I am able to connect to 8.1.7 database from other clients.
2)The 9.2 client is able to connect to some other database on the network which is 8.1.6.2.
3) I have cut and pasted tnsnames.ora from the working client( but that client is 8i client ).
4) this is the first time I am using this kind of configuration i.e., trying to access 8.1.7 server from 9.2 client. I tried to create new connection through NET CONFIGURATION ASSISTANT as per the documentation but it's not working.

Scenario:
Windows 7 laptop in a Windows Domain environment is attempting a straight RDP session to a non-Domain Windows server 2008 R2. Laptop (System A) gets rejected every time using correct local Administrator account and verified correct password on non-Domain
Windows 2008 R2 server (System B)
Any ideas or scenarios that may cause this kind of behavior (other than bad password which has been totally eliminated as a variable)???
Facts:
I can remotely log in to (System B) using LogMeIn and the Administrator account and password referenced above. I can also log in to (System B) from another non-Domain (System C) server using same credentials as above, without any problems. (System B) has
NO GPO's applied (verified by GPRESULTS) but I cannot speak to (System A). Owner of (System A won't help out anymore so I need some possible ideas or things that
may cause this kind of behavior)
User who has problem claims to also be able to log in to (System B) from a non-Domain Linux and Mac OSX box.

Hi,
As a workaround please add the following line to the .rdp file (using Notepad) that the user double-clicks to connect to the server:
enablecredsspsupport:i:0
If they do not have a .rdp file for this server they can create one easily by entering the name, configuring settings, etc., in the Remote Desktop Client and then clicking the Save As button.
After making the above change please have them verify that they are able to connect. If the change was performed correctly they should get the server logon screen instead of the frontside authentication prompt.
Thanks.

Not able to connect from linux client. Get TNS-12560: TNS:protocol adapter

Hi,
Details of the configuration :
Server:
RHEL4: 10.2.0.3 Oracle Enterprise Database installed.
SID = orcl, port 1521.
Client:
RHEL4 : 10.2.0.x client installed.
Whenever, I try to connect from Client to server, I get following error:
For tnsping orcl I get following error :
TNS-12560: TNS:protocol adapter error
I get the same error even, If I do a sqlplus "scott/tiger@orcl" with TNS_ADMIN, ORACLE_HOME everything set correctly.
On the server, I am able to connect to the same db without any problem. I have following env set ORACLE_HOME, TNS_ADMIN and PATH. Here, I am trying to make sure that the sqlplus goes through the listner.
Any help is appreciated. Please let me know if you need more information.
Thanks much.

Ensure your listener is properly configured and started. Check the listener's address and verify you can tnsping it with the tnsping command:
tnsping orcl
On the other side, make sure your tnsnames.ora file on the client side has properly configured the address where the listener is located.

Reporting services instance not able to connect from SSMS

Hi All,,
I have installed SQL SERVER 2012 on Windows 8.1. I configured report server in native mode.
* Reporting services is in started state
  * SQl server service is in started state
  * Sql serevr agent is in started state
  * SQL browser is in started state
When i tried to connect Report server instance using SSMS i got the below error.
TITLE: Connect to Server
Cannot connect to .
ADDITIONAL INFORMATION:
Unable to connect to the server at . The specified URL might not be valid or there might be a problem with the report server version or configuration. Specify a different URL, or contact your server administrator to verify that the report server runs SQL Server
2008 or later. Additionally, if you are trying to connect to a SharePoint-integrated report server, verify that SharePoint is installed on the server and that the report server uses SharePoint integrated mode. (Microsoft.SqlServer.Management.UI.RSClient)
BUTTONS:
OK
When i connect using http://localhost/reportserver I am getting below error
The permissions granted to user '' are insufficient for performing this operation.
Though i am the administrator
And when i connect using below URL http://localhost/reports
I get Unable to connect to the remote server
Please suggest your input on the problem

Hi Khushi N,
According to your description, you are administrator, when you tried to connect reporting services from SSMS, the error message occurred. When you tried to access report manager with the URL:
http://localhost/reportserver, you were prompted that the permissions granted to user '' are insufficient for performing this operation.
The Reporting Services error rsAccessedDenied occurs when a user does not have permission to perform an action. To troubleshooting this issue, please make sure that you have sufficient permission and the report server name is correct. You can use the reportserver
URL, e.g. HTTP ://<servername>/ReportServer, to log on the reporting service in SSMS.
In addition, by default, we could not access all of the report server properties available in SQL Server Management Studio unless we start Management Studio with administrative privileges. To configure Reporting Services role properties and role assignments
so you do not need to start Management Studio with elevated permissions each time, please refer to the following document:
From the Start menu, click All Programs, click SQL Server 2012, right-click Management Studio, and then click Run as administrator.
Connect to your local Reporting Services server.
In the Security node, click System Roles.
Right-click System Administrator and then click Properties.
In the System Role Properties page, select View report server properties. Select any other properties you want associated with members of the system administrators role.
Click OK.
Close Management Studio
The issue may be caused by the UAC or Internet Explorer security setting, please try to follow this steps:
1. Open the Internet options of the IE and add the report server URL into trusted site in the Security tab.
2. Run the IE as administrator.
For more information about Configuring a Native Mode Report Server for Local Administration, please refer to the following document:
http://msdn.microsoft.com/en-us/library/bb630430(v=sql.110).aspx
If you have any more questions, please feel free to ask.

Secondary domain controller not able to connect from work stations.

We are using primary and secondary domain controllers. In which the secondary domain controller act as a replication server. actually the problem occurs while accessing the secondary domain controller from work stations I get the following error:
"The trust relationship between this workstation and the primary domain failed".
Any one please give as a solution.
Thank you.

Hi,
Most simple resolution would be unjoin/disjoin the computer from the domain and rejoin the computer account back to the domain.
There might be multiple reasons for this kind of behavior.
Here are a few of them:
Single SID has been assigned to multiple computers.
If the Secure Channel is Broken between Domain controller and workstations
If there are no SPN or DNS Host Name mentioned in the computer account attributes
Outdated NIC Drivers.
According your description, the second one may be the cause of your problem.
When a Computer account is joined to the domain, Secure Channel password is stored with computer account in domain controller. By default this password will change every 30 days (This is an automatic process, no manual intervention is required).
Upon starting the computer, Netlogon attempts to discover a DC for the domain in which its machine account exists. After locating the appropriate DC, the machine account password from the workstation is authenticated against the password on the DC.
If there are problems with system time, DNS configuration or other settings, secure channel’s password between Workstation and DCs may not synchronize with each other.
A common cause of broken secure channel [machine account password] is that the secure channel password held by the domain member does not match that held by the AD. Often, this is caused by performing a Windows System Restore (or reverting
to previous backup or snapshot) on the member machine, causing an old (previous) machine account password to be presented to the AD.
Follow below link which explains typical symptoms when Secure channel broken,
Typical Symptoms when secure channel is broken

However the contrary does not works ! When I try to make FaceTime calls FROM the MB air or the Ipad to the Ipod , it hangs & disconnects . iMessage works perfectly both ways . Stranger than that , Face Time works without a glitch to the 4th gen Ipod , from an older MB black with system 10.7.5 ! Thanks in advance for your help .

Hi Anju,
please re-read what I wrote.
I didn't ask you to run
x_ping -n -d
but instead
x_ping -n <hostname of database server> -d <DBSID>
You've to fill in the correct values for
<hostname of database server>
and
<DBSID>
regards,
Lars

Dear all,
I have trouble to connect em console to database instance. My database is 11.2.0.3 and before this I did the patching from version 11.2.0.1, and now i cannot get fully functionality of em console.
error is:
Enterprise Manager is not able to connect to the database instance. The state of the components are listed below.
It shows that agent is connected, database and listener is up.
I did recreation, dropping and recreating with emca, but no success.
Did anyone have similar problems with em console?
Regards,

You need to first of all, Connect to the Database as SYSDBA (because your were not connected), then start the database (because it is not started).
If you already used the username and password in the command prompt and you are sure that the database is already stared, then you need to set the ORACLE_SID before you open SQLPlus. This is because if SQLPlus does not know the SID you are connecting to, it simply thinks it is not up or has no service hence the message "Connected to an idle instance".
