Abstract

A computer network analyzes a problem with a first computer in the network. The network comprises a first program which runs on a second computer and analyzes a problem with the first computer. A second program also runs on the second computer and generates an alert for transmission to the third computer. The alert includes a probable cause category encompassing the problem and a recommendation. The recommendation is to contact a service engineer if the problem requires expertise or resources of the service engineer to correct, and is to establish remote access on site at the third computer of the first program to obtain additional information relating to the cause of the problem if at least a reasonable chance exists that the problem can be corrected by a person at the first computer which person not having service engineering expertise or resources. A third program runs on the third computer and remotely controls the first program to obtain the additional information relating to the cause of the problem if there is at least a reasonable chance that the problem can be corrected by a person at the first computer which person not having service engineering expertise or resources. The additional information includes a recommended test or inspection to determine the cause of the problem.

Claims

1. A method for analyzing a problem with a first computer, said method comprising the steps of:

detecting a problem at said first computer;

running a program on a second computer to analyze the problem;

sending a notification of said problem to a third, remote computer, said notification including a probable cause category encompassing said problem and a recommendation, said recommendation being to call a service engineer if the problem requires expertise or resources of the service engineer to correct, and being to establish remote access on site at said third computer of said program to obtain additional information relating to the cause of said problem if at least a reasonable chance exists that said problem can be corrected by a person at said first computer which person not having service engineering expertise or resources; and

using said third computer to remotely control said program to obtain additional information relating to the cause of the problem if at least a reasonable chance exists that said problem can be corrected by a person at said first computer which person not having service engineering expertise or resources.

2. A method as set forth in claim 1 wherein after said step of remotely controlling said program, performing the step of making an oral communication by telephone to a person on site at said first and second computers to conduct a test or inspection to determine the cause of said problem based on said additional information.

3. A method as set forth in claim 1 wherein said additional information includes a recommended test or inspection to determine the cause of the said problem.

4. A method as set forth in claim 1 wherein said additional information narrows the probable cause of said problem within said probable cause category.

5. A method as set forth in claim 1 wherein said recommendation is to establish said remote control of said program running on said second computer.

6. A method as set forth in claim 1 wherein said recommendation is to call the service engineer to said first computer.

7. A method as set forth in claim 6 wherein another program runs on said third computer and automatically responds to said recommendation to call said service engineer, said other program being programmable to respond to said recommendation to authorize said second computer to call said service engineer and programmable to alert an operator at said third computer without authorizing said call to said service engineer.

8. A method as set forth in claim 7 wherein said program is programmable to automatically respond to said recommendation by directly calling a service engineer to said first computer.

9. A method as set forth in claim 1 wherein said remote control of said program running on said second computer includes the step of displaying screens on site at said third computer, said display screens being generated by said program and providing said additional information.

10. A method as set forth in claim 1 further comprising the step of running said program to identify a part which is the probable cause of said problem.

11. A method as set forth in claim 10 wherein said identification of said part is stored in said second computer and is not sent with said notification for use by said third computer.

12. A method as set forth in claim 6 wherein said second computer responds to said authorization to call said service engineer by transmitting to a service engineer dispatch facility an identification of a part which is the likely cause of said problem.

13. A method as set forth in claim 1 wherein said problem was or is due to a power loss external to said first computer, and said recommendation is to establish remote access on site at said third computer to obtain additional information relating to the cause of said problem.

14. A method as set forth in claim 1 wherein said problem is due to defective hardware, and said recommendation is to call a service engineer.

15. A method as set forth in claim 1 wherein said problem is due to a switch being in a wrong position, and said recommendation is to establish remote access on site at said third computer to obtain additional information relating to the cause of said problem.

16. A method as set forth in claim 1 wherein said probable cause category encompasses a plurality of actual problems.

17. A method as set forth in claim 1 further comprising the steps of:

updating said program to analyze a different type of problem; and

grouping said different type of problem within a pre-existing probable cause category, said pre-existing probable cause category encompassing at least one other type of problem that could be analyzed by said program before said update.

18. A computer network for analyzing a problem with a first computer, said network comprising:

a second computer coupled to said first computer, said second computer including a processor and means for receiving error signals of different types from said first computer;

a third computer remote to said first computer; and

means for communicating between said third and second computers; and

wherein

said second computer further comprises problem analysis means for generating alerts corresponding to the types of error signals received from said first computer and transmitting said alerts to said third computer, each of said alerts including a probable cause category encompassing said problem and a recommendation, said recommendation being to contact a service engineer if the problem requires expertise or resources of the service engineer to correct, and being to establish remote access to said second computer to obtain additional information relating to the cause of said problem if at least a reasonable chance exists that said problem can be corrected by a person at said first computer which person not having service engineering expertise or resources;

said second computer includes means for providing said additional information; and

said third computer includes means for remotely controlling said second computer to obtain said additional information relating to the cause of said problem if there is at least a resonable chance that said problem can be corrected by a person at said first computer which person not having service engineering expertise or resources.

19. A computer network as set forth in claim 18 wherein said additional information includes a recommended test or inspection to determine the cause of said problem.

20. A computer network, as set forth in claim 18 wherein said third computer further comprises response means for automatically responding to said recommendation to call said service engineer, said response means being programmable to respond to said recommendation by authorizing said second computer to call said service engineer and being programmable to alert an operator at said third computer of said recommendation without authorizing said second computer to call said service engineer call.

21. A computer network as set forth in claim 18 further comprising said first computer and wherein said first computer includes means for detecting problems within said first computer and generating said error signals for transmission to said second computer.
