Reminder

• Will not be covering Terminal Server

• Remote Desktop

• Using PC Anywhere type service

• Windows 2000 Server no longer supported

• All the above do connect but are not covered

Benefits

• Save time

• Be proactive

• Reassure clients

• Take home tools

Assumptions Made

• You know how to set folder permissions

• Know how to configure firewall and routers

• Recognized BIOS drive

• Understand the client/server environment

• Know how to configure a Server

• Understand TCP/IP jargon

Have you experienced these Error Messages

• Read Only

• Has experienced a network error…

• Cannot find connection manager…..

• Database has timed out……

• Simply Accounting cannot open the database….

• If you have not experienced these types of errors then this

session will give tools to enhance the connection manager’s

performance

Three main reasons for unable to connect

DHCP/DNS issues

.NET installation

Permissions

DHCP/DNS issues

• Like most programs Simply has incorporated .NET into its

report functionality

• Many advantages to have reports internet ready

• .NET must bind to the TCP/IP

• Problems develop if there is host name resolutions

DHCP/DNS Questions to ask

• Who is handing out the IP addresses

• Is the Workstation’s host name resolution different than the

Server

• Is there static IP addresses or dynamic

• Is the DNS server private or public

• Are private IP addresses being blocked

Host Name Resolution• Check if name is same as localhost name. (hostname)

• Search local DNS Client resolver cache. (ipconfig /displaydns )

• Query the designated DNS server (nslookup)

• If host name is < 16 characters, convert to NetBIOS name -> Lookup local

NetBIOS name cache. (Enable NetBIOS over TCP/IP)

• Query WINS server. (use nslookup debug mode check TCP/IP settings.

See wins query.txt on CD)

• Use ping to broadcast to local subnet 3 times

• Search local LMHosts file. C:\windows\system32\drivers\etc

DOT NetFramwork installation issues

On the server….. Check .NET installation

Check C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

Run utility tool (netfx_setupverifier.exe)

Uninstall using Add/Remove and Reinstall .NET with Simply

Run clean-up tool (cleanup tool.exe)

Visit Microsoft website for more cleanup options

Permissions and Authentication

Permissions Revisited

• Check the “log on as service” make sure the user is added as a service

• Use the network wizard

• Check mysqld-nt.exe process must be system (open up task manager)

• Super Admin user for Dell computers

• Upgrade yourself to a true admin user 'net user administrator /active:yes'

• If sharing parent folder do not share child

• As a TEST use the specialized data provided on the session CD

Q & A

Command Line Help

• mysqld-nt.exe (open the data without user interface)

• ipconfig (trouble shoot DNS issues)

• netstat (port avaliability)

• telnet (port avaliability over network)

• nslookup (DNS issues)

• using portquery (port avaliability on server)

mysqld-nt.exe

• To test MySQL without the connection manager

• Msqld-nt –h server –P 13540 C:\data\universl.saj

• If successful window will remain open

• Can open with MySql query and check data

TIME_WIAT is healthy… waiting for connectionMany other variations – b lists Simply and MySQL

Can also use freeware program ports watch for realtime activity

telnet

• Quick way to test if port is open

• Open data with Simply or mysqld-nt.exe

• telnet server<>name 13540

• telnet will time out after a few seconds

• telnet is often restricted by security policies

• Better to use queryports

nslookup output

Server: Unknown Adress:192.168.254

No response from server ….. DSL modem configuring

Cannot find server name for address : Timed out

There is no DNS server, possible connection problems

Cannot find server name for address 127.0.0.1: Timed out

There is a DNS server running somewhere but is not defined

Default Server: server.com Address 10.140.53.4

The best output, query server for name resolution

Nslookup (set type ns) to find which DNS servers are available –ping test

Port Query

• Find local server ports currently open (portqry.exe –local)

• Find Simply port local ( portqry -n 127.0.0.1 –e 13540 )

• Find port on a server ( portqry -n 10.152.21.4 –e 13540 –p udp)

• To specify a specific source port –sp 80 –n 10.152.20.53 –e 13540)

to identify if there are ports being filtered or block from workstation to server

• Find port on a server ( portqry -n 10.152.21.4 –e 13540 –p udp -sl)

to determine if there is a slow link

• Endless permutations and combinations

Registry Checks

• Reminder 2008 A and B controlset issue…. unable to map network drive

HKLM\SYSTEM\CurrentControlSet\Services\lanmanserver\shares

HKLM\SYSTEM\ControlSet001\Services\lanmanserver\shares

Check CD for more infor

• Busy server with many users it is possible to increase the number of ports

HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

MaxUserPort Data Type: REG_DWORD Value: 65534,

TcpTimedWaitDelay Data Type: REG_DWORD Value: 30

Check CD for technote

Checking the Error LogError in my_thread_global_end(): 2 threads didn't exit

Error: Cannot find table simply/tusrprf2 from the internal data dictionary

ERROR: the age of the last checkpoint is 3771360 which exceeds the log group capacity 3771188. If you are using big BLOB or TEXT rows, you must set the combined size of log files at least 10 times bigger than the…….

ERROR :Page dump in ascii and hex (16384 bytes): len 16384; hex 7d255d6e0000025f000002560000026800000000006190e945bf

Event Viewer – five different types

• .Net Runtime 2.0 Error

can signify damaged data or some .NET components are not installed properly

• MySQL

Will generate if there is a problem with the database structure ie. cannot find table

• Simply

Will generate if there is a problem with records when a query is run

• Simply Accounting Database connection manager

Will generate if the connection cannot load (1053/1069 errors)

• Side by Side errors

Ignore these errors, French foundation class not loaded

Q & A

Linux Review

• 2009 Linux driver available

• Redhat

• SuSE

• Rumour that the driver has been installed on other Linux flavours

• Mono 1.9 must be installed

• ODBC installed

Linux Gotha's

• Always install from command line root

• ODBC 5.0 will not work must uninstall and reinstall 3.5

• Do not install mono 2.0 from download. Install from install CD

• Run <command> do not rely on process report

• Do not run IP 6.0
