Server name cannot be resolved using VPN connection

I've just installed Windows Server 2012 and Exchange 2013. I previously was using Windows SBS 2008 with Exchange 2007 and I was able to connect to the server via VPN and create an Outlook account and connect to the Exchange server no problems.
Now with the WS2012 and Exchange 2013 everything is working fine but when I connect to the VPN from outside the network and try to create a new Exchange account in Outlook, I get the error "The name cannot be resolved. The connection to Microsoft Exchange
is unavailable. Outlook must be online or connected to complete this action."
When I'm on the VPN I can ping both server name and IP address no problems so that isn't the issue. I've searched the net and tried multiple things including turning off firewall on both sides.
To clarify my setup I have two WS2012 servers. One is DC and VPN server, other is Exchange 2013 server which has both CAS and Mailbox roles.
I have a suspicion that the issue is to do with certificates. I don't have a valid bought SSL certificate, I am just using self-signed certificate. Can anyone verify that this is the issue or could it be something else?
Thanks.

Hi,
Since you don't have a valid SSL certificate, you can try to manually configure Outlook to connect to your Exchange server by the following steps:
Go to your Outlook mail settings from Start > Control Panel > Mail > Show Profiles > Add.
If you cannot locate the Mail icon in Windows Control Panel, turn on Classic View (click
Classic View on the left side of the Control Panel window).
Specify your Profile Name and click OK.
On the Auto Account Setup page, select Manually configure server settings or additional server types and then click
Next.
On the Choose Service page, select Microsoft Exchange or compatible service and click
Next.
On the Server Settings page:
- Specify your Server FQDN as Exchange server name (you can find it in HostPilot® Control Panel >
Users & Services > Advanced Settings).
- Type your Exchange Mailbox Username (email address).
- For the Offline use option, make sure that Use Cached Exchange Mode is selected.
- Click the More Settings button and switch to Connection tab.
- In Outlook 2013 you can specify the time period for which email items will be kept offline.
Select the Connect to Microsoft Exchange using the HTTP option and click the
Exchange Proxy Settings button.
-Specify Exchange proxy settings.
-Type the URL for your proxy server in the Use this URL to connect to my proxy server for Exchange field.
You can find the correct URL in HostPilot > Users & Services > Advanced Settings.
-Make sure that both the options On fast networks and On slow networks are checked.
-In the Proxy authentication settings box, choose Basic Authentication.
If you want to have Outlook save your password, read the Knowledge Base article on
How do I save my Outlook Password? for more information.
Click OK, then Apply, then OK
to return to the Add New Account window. Click Check Name.
If you have set everything up properly, you will see a window requesting authentication.
Enter the complete primary email address as the username, and enter the password for the mailbox.
If you have entered the username and password correctly, the username will now be underlined, and the entry in the Microsoft Exchange Server field will also be underlined.
Note: If your server is Exchange 2013 the server name will get underlined and will resolve into a name that looks like
[email protected].
Such a conversion is expected behaviour for Exchange 2013 mailboxes.
Click Next, then Finish, then OK to save changes.
Start Outlook and log in, using the same credentials as in step 9.

HttpException Server name cannot be resolved

Within an application we need to connect via HTTPS using the server URL rather than the IP address as the certificate references the domain.
We always get the following error 'org.w3c.www.protocol.http.HttpException: The host name [gecwinfinite.com] couldn't be resolved. Details: "gecwinfinite.com"'
Via the browser we can connect to the server using the URL.
Any assistance would be appreciated

I have seen similar problems where reverse DNS was required by Java. Ensure you can perform a reverse DNS on the IP Address and try it again.

Cannot start Outlook 2013: "name cannot be resolved" / "connection to Microsoft Exchange is unavailable" / "___.ost is not an Outlook data file (.ost)"

My work e-mail has a double-login system, where my credentials for work access are one username and my e-mail is an alias of that first username, so they differ from one another. I suspect that's why I've been having the hardest time with Outlook 2013. I
was able to add my account just fine once but changed my mind about using Outlook and removed the account. Now I can't get back into Outlook for the life of me. The error messages that show up are:
1. It asks me to verify server and Mailbox. I've tried it with both usernames (the official work username and the e-mail alias) as my Mailbox info, followed by the email domain (even tried it without the domain) and it still won't verify when I click "Check
Name".
2. This message comes up: The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
3. Then once I click "OK" another pop-up says: Cannot start Microsoft Outlook. The file C:\Users\FirstLastname\AppData\Local\Microsoft\Outlook\FirstLastname.ost is not an Outlook data file (.ost).

Server Name cannot be blank

HI Every one.
This is prasad working on sap xmii with sql server 2005.I am having problems to add or update the table using query templates.When i am updating a table with data I am getting the sql error as server name cannot be blank.It is working fine in Sap Xmii11.5 but in Sap Xmii 12.0 iam getting this error.Can any help on this issue.
Thanks,
Prasad.

Server name cannot be blank errors mean that you are either referencing a display template or a query template that does not have a server property saved in it such as:
/XMII/Illuminator?QueryTemplate=Defaults/TagQuery
/XMII/Illuminator?QueryTemplate=Defaults/iChart
Double check the path to your template and confirm that it's a valid query template including a Data Server.

How do I find out my MBP's 'server name?' to run Remote Desktop Connection?

How do I find out my MBP's 'server name?' to run Remote Desktop Connection?

Hi Dave,
You need to type the server name that was assigned by your mail administrator for the server running Exchange. So please ask your administrator for the Server name. Thanks for your understanding.
For more information, here is an article for your reference.

3 WRV200 routers to create a 3 node WAN using VPN connections

I have looked through some of the other posts to see if this question had been asked before, and I didnt see anything.
I have 3 WRV200 that I want to install in 3 cities.
I want each router to have its own Internet connection from the local ISP.
I then want each router to connect to the other 2 routers and create a 3 node WAN using VPN connections.
This is what I think I need. I am hoping somone will correct me.
WRV200-CA
192.168.1.0 - CA Local LAN
192.168.1.1 Default Gateway
255.255.255.0 Subnet Mask
192.168.1.10 Static Assigned for Printer
192.168.1.11 Static Assigned for Printer
192.168.1.12 Static Assigned for Printer
192.168.1.13 Static Assigned for Printer
192.168.1.101 - 120 DHCP addresses for workstations
WRV200-NYC
192.168.2.0 - NYC Local LAN
192.168.2.1 Default Gateway
255.255.255.0 Subnet Mask
192.168.2.10 Static Assigned for Printer
192.168.2.11 Static Assigned for Printer
192.168.2.12 Static Assigned for Printer
192.168.2.13 Static Assigned for Printer
192.168.2.101 - 120 DHCP addresses for workstations
WRV200-LI
192.168.3.0 - LI Local LAN
192.168.3.1 Default Gateway
255.255.255.0 Subnet Mask
192.168.3.10 Static Assigned for Printer
192.168.3.11 Static Assigned for Printer
192.168.3.12 Static Assigned for Printer
192.168.3.13 Static Assigned for Printer
192.168.3.101 - 120 DHCP addresses for workstations
I know how to get the public IP address that is assigned to the broadband modem by each of the ISPs.
Do I have to connect to each of the other public IP addresses to create this 3 location WAN?
I dont think this is the best way since the IP address might change since it is assigned by the ISP via DHCP.
Should I create a 192.168.4.0 network with a 255.255.255.248 subnet mask. and give each router its own address within the .4 network? Im not sure where to do this if its different from the local LAN IP addresses listed above.
Do I have to have 2 cable modems at each location in order to create a point to point connection with the other 2 routers?
It seems like I should be able to send 2 seperate VPN signals over the same cable modem in order to connect with the other 2 routers.
If 192.168.x.x is non routable, how is a PC at 192.168.1.101 going to route through to the local cable modem and connect to the cable modem that is in NYC, and then print to the printer located at 192.168.2.11
Ultimately I want to:
1. print to any printer at any of the 3 locations.
2. Remote Desktop into any workstation at any of the 3 locations.
3. Connect to the Internet via a public WiFi hotspot and use my laptop that would have some type of software that would allow me to connect to any of the 3 LANs.
Thank you in advance.

Appendix D of the RVS4000 admin guide has an example of configuring a site-to-site VPN tunnel between 2 routers that have dynamic WAN IP addresses. For your scenario, you can configure a site-to-site tunnel between each pair of WRV200 routers.

Receiving emails about a newly set up itunes account that does not belong to me (although has my name). The address used in connection with it seems to be in California and the person likes Justin Bieber - what's going on here?

Hi. I am receiving emails about a newly set up itunes account that does not belong to me (although has my name). The address used in connection with it seems to be in California and the person likes Justin Bieber (as I now have a receipt for that purchase). It states that it is billed to store credit. (a) I don't want to receive this person's information and (b) I certainly don't want to somehow be charged for it (although it appears, thus far, that I have not been). What's going on?

i didn't read a lot of your 2nd paragraph, but it seems like the password is the issue, right?
do a true clean install
reboot your machine and hold down command+option+r, you should see a spinning globe - if you don't see the globe or anything that reads internet recovery, shut down and try again
at menu, chose disk utility and once there, find your HD on the left side, select the physical name and erase it as mac journaled
exit disk utlity
at menu, choose install OSX
this time, when it asks for a password just hit continue, it will let you complete without a password
you should be able to get into your laptop, now figure out what password you'll be able to use with your kb issue

How can I use VPN connection to access my Outlook email?

My company doesn't support iPhone's so I can't get any help from them -- here is my problem:
We run Outlook 2003 and they won't tell me the server name for Outlook. I have been able to connect to our Cisco VPN and access internal webpages, etc. Is there anyway I can use this VPN connection to retrieve my Outlook email?
Or is there anyway I can identify the server name I need to allow the iphone to connect to my Outlook?
Any help would be much appreciated.

Yes, it is possible to connect via VPN. However,if IT hasn't set up ActiveSync on the internal Exchange server, this won't work anyway.
The server name for your Exchange server is in the configuration of Outlook, so you can find it and use that to connect. But that doesn't mean that things are set up correctly to have this work.
To find your server name, (this is for Outlook 2007), Tools->Options and double-click on the account under the Email tab. The server name is next to "Microsoft Exchange server" on that screen.

The host name cannot be resolve ? ( with linksys router )

Hi all, I have some problem with setting up a network. I tried to set my network according to http://wiki.archlinux.org/index.php/Configuring_network the network/internet is fine except the host name with "http://" cannot be resolve. For example
ping 216.239.61.104
ping www.gogle.com
both work fine, until I try,
ping http://www.google.com
it give me error, tell me that the hostname cannot be resolved. I tried to config my network using both dhcp or fix-ip, but the problem still present in both way. Internet works fine in windows/ubuntu.
Anyboy has any clue ? The router I use is wrt54gl with tomato firmware.
thanks in advance.

Hi,
if pinging www.google.com works then dns resolving _does_ work. Why would you want to ping http://something?
You should try opening http://whatever in a browser not pinging it from command line.
Or am I missing something obvious?
Yes, for instance, all mirror list for pacman is in "http://...." or "ftp://...." form. I could easily change the repository list, but I'm not sure if it'll have same problem in future with other program. Also, if it work in ubuntu and windows, why not arch.

Dear Ejp,
I would like to first share a simple case here first. Below is the simplied codes. Here I dont need any import statement. I keep both this in the same directory. I am using this command to compile javac callSMSClient.java. Why even this simple case is not working?
public class callSMSClient{

     SMSClient t1 = new SMSClient(1);

Cannot establish a working VPN connection...period

I am going nuts. I have been trying to get a vpn connection established for two weeks. I am using a Linksys BEFVP41 router and have tried to connect with Snow Leopard's built-in Cisco ipsec vpn, IPSecuritas, and VPN Tracker. No luck. I'm willing to replace the router with anything that will work. My office network consists of a vpn router, a droboshare that I want to be able to access remotely, and three office macs - two of the macs are MacBook Pros on which I want to be able to set up vpn connections. Any suggestion on a router, vpn client, configuration settings files, etc. would be greatly appreciated.

Use VPN connection as a listen network interface in Web Application proxy

I have a test environment: domain in hyper-v with Sharepoint and Office Web Apps servers (all under Windows 2012 - Windows 2012 R2).
Because my home ISP does not permit some inbound ports (80,443) in a gate machine (under Windows 2012 R2) I create a vpn connection (by "setup a new connection or network") to my outside vpn server. On this vpn server the ports forwarding is configured
and work fine (f.e. default IIS site is visible).
I try to public my Sharepoint 2013 Foundation in Internet over this vpn connection and faced with the problem - WAPx (Web application proxy) does not bind to this vpn connection, only to traditional network interfaces.
The question is how to make listening WAPx the VPN interface?

Websphere Application Server 5.1 Hangs when using Oracle Connection Pool

I have a j2ee application that runs on WAS 5.1 ( IBM JDK 1.4 ) and Oracle 10g 10.2.0 . My customer is doing load testing with 25 virtual users and a connection pool with a max size of 10. When the test starts all 25 users attempt to get a connection, and the first 10 get a connection. At this point the application server hangs with the connection pool in allocation. This is seen in Tivoli. Each thread only needs one connection to process it's request.
I have my own home grown connection pool which when used under this load does not experience and issue. Monitoring from Oracle's admin console I see a max of 10 sessions. The home grows connection pool does not use a WAS DataSource.
I have configured my application to use DB2 with a WAS DataSource and the application server does not hang. Monitoring using Tivoli shows the connection pool going into allocation, but it recovers as is expected.
Are there any known issues with the Oracle JDBC drivers when used with WAS 5.1 DataSources?
Any direction would be helpful, as I currently thing there is an issue with Oracle's Connection Pool and the IBM JVM.
Thanks,
J

just an attention call: OracleDatasource connection pool does not accept parameters such as removeAbandoned, minEvictableIdleTimeMillis, timeBetweenEvictionRunsMillis, etc, these are specific for the tomcat dbcp implementation (http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html#JDBC_Data_Sources).

Cannot send message using server icloud, cannot send message using server icloud

Whenever I try to send a message from my iCloud mail id using Lions mail client I get the following
The server “p08-smtp.mail.me.com” cannot be contacted on the default ports.
Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent.
I saw an articale suggesting trying to change the SMTP server to SMTP.MAIL.ME.COM but when I try that I get address rejected
Sending mail through the web interface seems to work OK
Any ideas?

I did some looking around and think I've got the right answer. if I use networktool to do a lookup of p08-smtp.mail.me.com it returns address not found.
It looks like p01-smtp to p04-smtp are defined but the others aren't.
I created a new smtp server and called it icloud2 and used the address p04-smtp.mail.me.com with the usual settings of USE SSL and AUthentication = Password (and gave it my iCLoud login details).
Associating that SMTP server with my iCloud account in mail.app lets me send perfectly.
I assume this is just apple not having everything not set up and replicated to DNS servers yet so I'm checking to see if p08 exists every couple of days and I'm move my iCLoud account to the normal SMTP server when I start getting nslookup responses.
