Finder sidebar connection to 'shared' server keeps failing

I'm on the same network being managed by Windows Small Business Server 2011, and I'm running Lion. I was always able to connect to the server via the sidebar in finder no problem. Yesterday our internal firewall wacked out and everyone lost connection to the server/internet. It took a few hours to get the firewall restored, and now I can't connect to the server anymore via the sidebar. All the 'shared' listing show up that are supposed to, and I can connect to ones that I wasn't connected to at the time the firewall went down, but I can't connect to the server now. I ran the Consol app and tried connecting, here's the error that showed up 'SharePointBrowser::handleOpenCallBack returned 61'. The popup either shows one of two messages on any given try:
'Check the server name or IP address, and then try again. If you continue to have problems, contact your system administrator.'
OR
'This file server will not allow any additional users to log on. Try to connect again later.'
Is there a way to just 'reset' these connections or something, or clear some cache and make it think its the first time again? It seems like it panicked once it lost connection and maybe something got corrupt? There's another Mac on the network (iMac also running Lion) that this is happening to as well. Any help is greatly appreciated, I've tried a ton of things from searching online with no success. Oh, I should mention that I am able to connect to it via Go->Connect to Server and using the IP address or the hostname. Just not from the sidebar anymore.

Same here. I just hired a new employee a few weeks ago and she's spent more time watching the spinning beach ball of death than putting in billing hours! Happens when the laptops are on the ethernet connection or wireless, worse with wireless. With so many projects and multiple people working on them it is impractical and illogical to drag files onto multiple computers. This all worked just fine before. I've wasted so much time trying to work around this and it's wasting so much $$ a day it's making me crazy. Hello Apple, pretty please......

Quit the maill app completely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Or go to Settings>Mail, Contacts, Calendars>Your email account >Mail>Off. Restart the iPad and go back to settings and turn mail on again and see if that works.
Or try this as well ....Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Who is your email provider? Have you checked with them to make sure you're using the correct settings when setting up an account on a mobile device? And what does auto-browsing have to do with using email?

Hi please help I have an Iphone 3 G S it is using the 5.1.1 ios upgrade which it has had for sometime although there was a minor update last evening ? My phone worked fine until arround 1 pm today then it stopped getting mail from my hotmail account along with the hotmail I am not longer able to see any updates to my calendar and most of my contacts have dissapeared.

I have no windows machines so it's only my laptop and desktop both running linux that I need to connect to this. I have tried googling and searching these forums to no avail
Thanks for any help that can be offered
Mike

If I run the following (on the machine I'm trying to set up the share)
smbclient -L localhost -U%
I got the following output
Connection to localhost failed (Error NT_STATUS_CONNECTION_REFUSED)
so I thought it might be something incorrect with the iptables side of things, however I haven't really touched that at all and it seems to look correct
iptables -nvL
Chain INPUT (policy ACCEPT 667 packets, 79977 bytes)
pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 157 packets, 20724 bytes)
pkts bytes target prot opt in out source destination
So from my (very little) knowledge this appears correct (I think)... However it appears that something is blocking access somewhere.

NW2004s Connect to Message Server Host Failed - BW to Portals connection

Hi,
I am trying to connect a SAP BW NW2004s Patch 8 system to a NW2004s Portal. All of the checks in RSPOR_SETUP are successful.
However when I try to launch a query from Bex Query it fails with the following message.
"Connect to message server host failedConnect_PM TYPE=B MSHOST=SAPMSCR6 GROUP=webshop1_biw R3NAME=CR6 MSSERV=01 PCS=1"
The message server entry in the System Landscape object for the BW Server is "SAPMSCR6". Is this right?
I have searched for information about this and can't find anything. I am sure it is something basic. As anyone else resolved this issue or do they have an idea what might be causing the problem?
Any suggestions gratefully received.
Dave

Guys look at the below SAP note. it will help

Connection to shared services provider failed

I am using:
Hyperion Planning 11.1.2.2
smart view 11.1.2.2.310
Microsoft Office 2010
Windows 8
When trying to connect from Excel with SmartView, i have the error, "Connection to shared services provider failed. The provider running at... is not a valid Shared Server provider."
I had test to connect in other PC and it works fine. Besides, i tried to connect to 2 servers (Development ande Production) and the same error is shown.
I had uninstall and install SmartView and nothing changed. I tried Smart View11125000 and the same error is shown.
Somebody know about this issue? or can help me??

What happens if you use a browser and type the shared connection url in it?
Did you try connecting using a private connection?

I tried to go thru the thread. I did not find any clue as why only server connectivity is failing. ABAP trial version is running fine and the NW trial version is working fine too. These run without crashing. I did a lot of customizing on the portal but dont see any issues except the System Connectivity. Like I mentioned I did UME configuration to point to NSP ABAP instance and I can log into the portal with user credentials that I use to login to ABAP. I can launch webgui etc without any issues.

"A connection to the server has failed" occurs in 3 minitues

I have deployed a web application(ADF) that inserts batch of records(over 50k) to the DB and client is expected to wait for the response.
But after client invoke the insert browser produce "A connection to the server has failed" java script error exactly after 3 minutes.
So the connection between client and Web Logic 10.3 is failing. Insert to DB continues to work.
Is this due to a timeout, why this error comes? How to configure web logic to avoid this.
-Prasad

PR,
You've been given some advice on the ADF forum in terms of how to deal with this (e.g., make the process asynchronous and use an af:poll/af:progressBar to keep the user informed).
Expecting a single HTTP request to work without timing out when you insert 50,000 rows one-by-one into the database is unrealistic.

A connection to the server has failed

Hi all,
I am getting this javascript pop up error ("A connection to the server has failed") in SOA 11g enterprise manager console. When i provide input to the BPEL process and click Test Web Service i get this message.
Can anyone throw some pointers on this?
Thanks in advance

But in my input payload i have five inputs. When i provide all the five i dont see any error. But when i provide only one input this error pops up. But any one of the input is enough to trigger the process.
Do you see an issue in this? No, I don't think this will cause a server connection issue. Can you check server logs and paste any error information you find there, here in this thread.
Regards,
Anuj

How to solve "connection to the server has failed"

Keep getting the following message - connection to the server has failed. So now unable to send or recieve E Mails

in Settings > Mail, Contacts, Calendars > Accounts check that the settings for the problem account are correct according to what your email provider requires.
In you still have problems try deleting the account and reinstalling it.
Also check, of course, to make sure that your e-mail provider has not been having technical problems.

Hi,
This JCO Exception caused by network problems, connection breakdowns, gateway problems, unavailability of the remote SAP system, etc.
What you can do is: Get the host of the SAP System from dev_jrfc.trc or the JRFC trace; ping the SAP system from command line; check routers, gateways, SAP systems
If an error has occurred on a lower communication layer, for example an RFC_ERROR_COMMUNICATION or RFC_ERROR_SYSTEM_FAILURE exception, have a look at the dev_jrfc.trc files. These files are written by JRFC and can be found in the directories j2ee/cluster/server* of the J2EE Application Server Installation.
Please check this blog and link:

The message server value under WebDynpro content admin is created with right values as i checked with Basis person.
My service file in C:/windows/system32/drivers/etc has entries for both J2EE stack entry and ABAP stack (on remote server) entry with port numbers.
When i ping the ABAP (remote server) from my machine command prompt I get response.
I am running out of options. I really appreciate your inputs.
Ramesh

Hi, I think this might have todo with the fact that your Java stack wants to connect with a server from the same logon group called "PUBLIC".
Please make sure you added the same logon group "PUBLIC" to the ABAP Server. Try transaction SMLG.
Also as posted above the SLD needs this info aswell.
After using the transaction SMLG, log in and out 5 times in a row to your ABAP stack using SAP GUI. This might actually force an update to the SLD.

Dedicated Server Connection Vs Shared Server Connection

Hi Gurus,
I have few doubts regarding Dedicated Server Connection Vs Shared Server Connection -
1) How do I know which connection mechanism is configured in my system.
2) Which connection faster and reliable.
3) Is there any risk to using shared server connection?
4) Which concept is new comparatively?
5) It is possible to restrict specific user for Dedicated Server Connection and other for Shared Server Connection in a same database.
Regards,
Atanu

Thanks for your post.... but still i have doubt on below points -
1) How do I know which connection mechanism is configured in my system.Search for dispatcher parameter (both words in the search box) in the docs.
2) It is possible to restrict specific user for Dedicated Server Connection and other for Shared Server Connection in a same database.You might be able to do something like this by using the RULE parameter with cman, limiting specific users (via local security setups) to specific client IP's and forcing them to particular service names. This is a net services issue, so does not conflict with what Billy said. It assumes you control whether your users will query the db appropriately, too. Many apps don't do that right.
